{{TNT|PD Help Page}}
<translate>
<!--T:1-->
This page explains the '''image''' syntax when editing the wiki.</translate>
<translate>
<!--T:2-->
You or another user must usually [[<tvar|managing>Special:MyLanguage/Help:Managing files</>|upload an image]] before you can use it on a page.

<!--T:3-->
Images that are stored on a MediaWiki server are usually rendered by using the <tvar|file><code>File:</code></> namespace prefix (but the legacy <tvar|image><code>Image:</code></> namespace prefix is still supported as a synonym) as the target of a MediaWiki link.</translate>
<translate>
<!--T:4-->
The alternate <tvar|media><code>Media:</code></> namespace prefix is also usable to reference the original media file content (for rendering or downloading it separately, out of any MediaWiki page).

== Supported media types for images == <!--T:5-->

<!--T:6-->
The following file formats are supported by default:

<!--T:7-->
* .jpg or .jpeg : bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).</translate>
<translate>
<!--T:8-->
* .png : bitmap image in the ''[[w:Portable Network Graphics|Portable Network Graphics]]'' format (specified by the ''W3 Consortium'').</translate>
<translate>
<!--T:9-->
* .gif : bitmap image in the legacy ''Graphics Interchange Format''.

<!--T:10-->
Other formats used on Wikimedia, and commonly enabled elsewhere (these may require extra set-up beyond what is enabled by default):

<!--T:11-->
* .svg : scalable image in the ''Scalable Vector Graphics'' format (specified by the ''W3 Consortium'').</translate> <translate><!--T:12-->
See [[<tvar|man>Special:MyLanguage/Manual:Image Administration#SVG</>|Manual:Image Administration#SVG]].</translate>
<translate>
<!--T:13-->
* .tiff : Tagged image format.</translate> <translate><!--T:14-->
Often used for high-resolution archival photographs.</translate> <translate><!--T:15-->
Often used with <tvar|ext>{{ll|Extension:PagedTiffHandler}}</>.</translate>
<translate>
<!--T:16-->
* .ogg, .oga, .ogv : Ogg multimedia (audio or video).</translate> <translate><!--T:17-->
Not an image format, but treated similarly.</translate> <translate><!--T:18-->
Often used with <tvar|ext>{{ll|Extension:OggHandler}}</></translate>
<translate>
<!--T:19-->
* .pdf : multipaged documents in the ''Portable Document Format'' (initially specified by ''Adobe'').</translate> <translate><!--T:20-->
Often used in conjunction with <tvar|ext>{{ll|Extension:PdfHandler}}</></translate>
<translate>
<!--T:21-->
* .djvu : multipaged bitmap documents in the ''DejaVu'' format (most often, scans of books).</translate> <translate><!--T:22-->
See <tvar|man>{{ll|Manual:How to use DjVu with MediaWiki}}</></translate>
<translate>
<!--T:23-->
*: Only a single page of a .pdf or .djvu file is shown at one time.

<!--T:24-->
Other media types may be supported, but it may not be possible to display them inline.

== Rendering a single image == <!--T:25-->

=== Syntax === <!--T:26-->

<!--T:27-->
The full syntax for displaying an image is:
</translate>
 <nowiki>[[</nowiki>File:''filename.extension''|''options''|''caption'']]

<translate>
<!--T:28-->
where ''options'' can be zero or more of the following, separated by pipes ('''|'''):

<!--T:29-->
* ''[[<tvar|1>#Format</>|Format]]'' option: one of '''border''' and/or '''frameless''', '''frame''', '''thumb''' (or '''thumbnail''');</translate>
<translate>
<!--T:30-->
*: Controls how the rendered image is formatted and embedded in the rest of the page.</translate>
<translate>
<!--T:31-->
* ''[[<tvar|1>#Size and frame</>|Resizing]]'' option: one of</translate>
<translate>
<!--T:32-->
** ''{width}'''''px''' — Resizes the image to fit within the given maximum width in pixels, without restricting its height;</translate>
<translate>
<!--T:33-->
** '''x'''''{height}'''''px''' — Resizes the image to fit within the given maximum height in pixels, without restricting its width;</translate>
<translate>
<!--T:34-->
** ''{width}'''''x'''''{height}'''''px''' — Resizes the image to fit within the given width and height in pixels;</translate>
<translate>
<!--T:35-->
** '''upright''' — Resizes an image to fit within reasonable dimensions, according to user preferences (suitable for images whose height is larger than width).</translate>
<translate>
<!--T:36-->
*: Note that the image will always retain its aspect ratio, and can only be reduced (not increased) in size unless it's in a scalable media type (bitmap images cannot be scaled up).</translate>
<translate>
<!--T:37-->
*: The default maximum size depends on the ''format'' and the internal image dimensions (according to its media type).</translate>
<translate>
<!--T:38-->
* ''[[<tvar|1>#Horizontal alignment</>|Horizontal alignment]]'' option: one of '''left''', '''right''', '''center''', '''none''';</translate>
<translate>
<!--T:39-->
*: Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).</translate>
<translate>
<!--T:40-->
* ''[[<tvar|1>#Vertical alignment</>|Vertical alignment]] option'': one of '''baseline''', '''sub''', '''super''', '''top''', '''text-top''', '''middle''', '''bottom''', '''text-bottom''';</translate>
<translate>
<!--T:41-->
*: Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is '''middle''').</translate>
<translate>
<!--T:42-->
* ''[[<tvar|1>#Altering the default link target</>|Link]] option'': one of</translate>
<translate>
<!--T:43-->
** '''link='''''{target}'' — Allows to change the target (to an arbitrary page title, or URL) of the generated link, activable on the rendered image surface; e.g. <tvar|code><code><nowiki>[[File:Example.jpg|20px|link=http://www.wikipedia.org]]</nowiki></code></> renders as <tvar|code2>[[File:Example.jpg|20px|link=http://www.wikipedia.org]]</> (external link), or <tvar|code3><code><nowiki>[[File:Example.jpg|20px|link=MediaWiki]]</nowiki></code></> renders as <tvar|code4>[[File:Example.jpg|20px|link=MediaWiki]]</> (internal link).</translate>
<translate>
<!--T:44-->
** '''link=''' (with an empty value) —  ({{mediawiki|rev:41727|MediaWiki 1.14+}}) Displays an image without any activable link; e.g. <tvar|code1><code><nowiki>[[</nowiki>File:Example.jpg|20px|link=]]</code></> renders as <tvar|code2>[[File:Example.jpg|20px|link=]]</>.
</translate>
<!--*** '''!''' Link does '''not''' work with thumb, thumbnail or frame. (This works for external and internal links)-->
<translate>
<!--T:45-->
*** '''!''' If you set <code>|link=|</code> (empty), then no <code>title</code> will be rendered. (See [[bugzilla:21454]].)</translate>
<translate>
<!--T:46-->
* Other specific options:</translate>
<translate>
<!--T:47-->
** '''alt='''''{alternative text}'' — ({{mediawiki|rev:41837|MediaWiki 1.14+}}) Defines the alternative text (maps to the HTML attribute <code>alt="..."</code> of the generated <code>&lt;img /&gt;</code> element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).</translate>
<translate>
<!--T:48-->
** '''page='''''{number}'' — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file).</translate>
<translate>
<!--T:49-->
** '''class='''''{html class}'' — (MediaWiki 1.20+) Defines classes (maps to the HTML attribute <code>class="..."</code> of the generated <code>&lt;img /&gt;</code> element).</translate>
<translate>
<!--T:50-->
** '''lang='''''{language code}'' — (MediaWiki 1.22+) For SVG files containing [http://www.w3.org/TR/SVG/struct.html#SwitchElement &lt;switch&gt;] statements varying on a ''systemLanguage'' attribute, selects what language to render the file in. The default is always English, even on non-English wikis.

<!--T:51-->
If a parameter does not match any of the other possibilities, it is assumed to be the caption text.</translate>
<translate>
<!--T:52-->
Caption text shows below the image in '''thumb''' and '''frame''' formats, or as tooltip text in any other format.</translate>
<translate>
<!--T:53-->
Caption text displayed in the '''thumb''' and '''frame''' formats may contain wiki links and other formatting.</translate>
<translate>
<!--T:54-->
MediaWiki extensions can add additional options.

<!--T:55-->
If 'alt' is not specified and a caption is provided, the alternative text will be created automatically from the caption, stripped of formatting.
</translate>

{{anchor|Format}}
<translate>
=== Format === <!--T:56-->

<!--T:57-->
The following table shows the effect of all available formats.
</translate>

{{ {{TNTN|Help:Images/frame}}|frame=thumb|ex=<translate><!--T:65-->
'''thumb''' or '''thumbnail'''</translate>|float=yes|inline=no|render caption=yes}}
|}

<translate>
<!--T:66-->
When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option <code>upright=N</code>, where N is the image's aspect ratio (its width divided by its height, defaulting to 0.75).</translate>
<translate>
<!--T:67-->
The alternative is to specify the desired maximum height (in pixels) explicitly.

<!--T:68-->
Note that by writing <code>thumb={filename}</code>, you can use a different image for the thumbnail.
</translate>

{{anchor|Size and frame}}
<translate>
=== Size and frame === <!--T:69-->

<!--T:70-->
Among different formats, the effect of the size parameter may be different, as shown below.

<!--T:71-->
* For how it appears when its size is not specified, see [[<tvar|1>#Format</>|Format]] section above.</translate>
<translate>
<!--T:72-->
* When the format is not specified, or only <code>border</code>ed, the size can be both reduced and enlarged to any specified size.</translate>
<translate>
<!--T:73-->
* In the examples below, the original size of the image is 400 × 267 pixels.</translate>
<translate>
<!--T:74-->
* An image with <code>frame</code> always '''ignores''' the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.</translate>
<translate>
<!--T:75-->
* The size of an image with <code>thumb</code> can be reduced, but can not be enlarged beyond the original size of the image.

|}

{{anchor|Vertical alignment}}
<translate>
=== Vertical alignment === <!--T:89-->

<!--T:90-->
The vertical alignment options take effect only if the image '''is''' rendered as an inline element and '''is not''' floating.</translate>
<translate>
<!--T:91-->
They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

<!--T:92-->
Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.

<!--T:94-->
Notes:

<!--T:95-->
# The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:</translate>
<translate>
<!--T:96-->
#* the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).</translate>
<translate>
<!--T:97-->
#* the additional line spacing which may be added by superscripts and subscripts.</translate>
<translate>
<!--T:98-->
# However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).</translate>
<translate>
<!--T:99-->
# The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.</translate>
<translate>
<!--T:100-->
# The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span).</translate> <translate><!--T:101-->
When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.</translate>
<translate>
<!--T:102-->
# The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and ''may'' depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

=== Stopping the text flow === <!--T:103-->

<!--T:104-->
On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image.</translate>
<translate>
<!--T:105-->
Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, <nowiki>== My Header ==</nowiki>) to appear to the right of the image, instead of below it, as a user may expect.</translate>
<translate>
<!--T:106-->
The text flow can be stopped by placing '''<tvar|code1><nowiki><br clear=all></nowiki></>''' (or if you prefer, <tvar|code2><nowiki><div style="clear: both"></div></nowiki></>) before the text that should start below the floating image.</translate>
<translate>
<!--T:107-->
(This may also be done without an empty line by wrapping the section with the floating images with <tvar|code><nowiki><div style="overflow: hidden">…</div></nowiki></>, which clears all floats inside the <code>div</code> element.)

<!--T:108-->
All images rendered as blocks (including non-floating '''center'''ed images, '''left'''- or '''right'''-floating images, as well as '''framed''' or '''thumbnail'''ed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them).</translate>
<translate>
<!--T:109-->
They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).

: <translate><!--T:122-->
Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.</translate>

== Rendering a gallery of images == <!--T:123-->

=== Gallery syntax === <!--T:124-->

<!--T:125-->
It's easy to make a gallery of thumbnails with the <tvar|gallery><code><nowiki><gallery></nowiki></code></> tag.</translate>
<translate>
<!--T:126-->
The syntax is:
</translate>
<pre>
<nowiki><gallery></nowiki>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>
</pre>

<translate>
<!--T:127-->
Note that the image code is not enclosed in brackets when enclosed in gallery tags. 

<!--T:128-->
Captions are optional, and may contain wiki links or other formatting.</translate>
<translate>
<!--T:129-->
Some of the parameters controlling thumb output can also be used here, specifically the ones that modify the file (as opposed to ones that control where in the page the image falls).</translate>
<translate>
<!--T:130-->
For example, with multi-paged media like pdfs, you can use code like <tvar|code><code>page=4</code></>.

<!--T:131-->
The <tvar|file><code>File:</code></> prefix can be omitted.

<!--T:132-->
For example:
</translate>

<source lang="moin">
<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
Example.jpg|on page "{{PAGENAME}}"
File:Using Firefox.pdf|page=72
</gallery>
</source>

<translate>
<!--T:133-->
is formatted as:
</translate>

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
Example.jpg|on page "{{PAGENAME}}"
File:Using Firefox.pdf|page=72
</gallery>

==== Mode parameter ==== <!--T:134-->
</translate>
{{MW 1.22|and after}}
<translate>
<!--T:135-->
Starting in 1.22 we have an experimental <tvar|mode><code>mode</code></> parameter, taking options as follows:

<!--T:136-->
* <tvar|traditional><code>traditional</code></> is the original gallery type used by MediaWiki.</translate>
<translate>
<!--T:137-->
* <tvar|nolines><code>nolines</code></> is similar to <tvar|traditional><code>traditional</code></>, but with no border lines.</translate>
<translate>
<!--T:138-->
* <tvar|packed><code>packed</code></> causes images to have the same height but different widths, with little space between the images.</translate> <translate><!--T:139-->
The rows in this [[w:Responsive web design|responsive]] mode organize themselves according to the width of the screen.</translate>
<translate>
<!--T:140-->
* <tvar|overlay><code>packed-overlay</code></> shows the caption overlaid on the image, in a semi-transparent white box.</translate>
<translate>
<!--T:141-->
* <tvar|hover><code>packed-hover</code></> is similar to <tvar|overlay><code>packed-overlay</code></>, but with the caption and box only showing up on hover.

<!--T:142-->
For example:
</translate>

<source lang="moin">

=== Optional gallery attributes === <!--T:145-->

<!--T:146-->
The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:
</translate>

<pre><gallery {parameters}>
{images}
</gallery></pre>

<translate>
<!--T:147-->
* <code>caption="{caption}"</code>: (caption text between double quotes for more than a word) sets a caption centered atop the gallery.</translate>
<translate>
<!--T:148-->
* <code>widths={width}px</code>: sets the widths of the images, default 120px.</translate> ''<translate><!--T:149-->
Note the plural, width'''s'''</translate>''.
<translate>
<!--T:150-->
* <code>heights={heights}px</code>: sets the (max) heights of the images.</translate>
<translate>
<!--T:151-->
* <code>perrow={integer}</code>: sets the number of images per row.</translate> <translate><!--T:152-->
0 means automatically adjust based on width of screen.</translate>
<translate>
<!--T:153-->
* <code>showfilename={anything}</code>: Show the filenames of the images in the individual captions for each image (1.17+).</translate>
<translate>
<!--T:154-->
* <code>mode={traditional|nolines|packed|packed-hover|packed-overlay}</code>: See section above (1.22+).
</translate>

{{note|<translate><!--T:155-->
The widths and heights parameters are taken more as suggestions than strict values for packed (and related) modes.</translate> <translate><!--T:156-->
Packed modes will adjust the width of images in order to make each row the same length.</translate>}}

<translate>
<!--T:157-->
Example:

<!--T:158-->
Coding:
</translate>

<pre>
<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">

== Row of images that will wrap to browser width == <!--T:160-->

<!--T:161-->
One way that works for a row of images with varying widths is not to use "thumb" or "left" or "none".</translate>
<translate>
<!--T:162-->
If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width.</translate>
<translate>
<!--T:163-->
If necessary, narrow the browser window to see the images wrap to the next row. 
</translate>

<pre>
[[File:Example.jpg|220px]]
[[File:Example.jpg|100px]]
[[File:Example.jpg|150px]]
[[File:Example.jpg|250px]]
[[File:Example.jpg|200px]]
[[File:Example.jpg|50px]]
[[File:Example.jpg|220px]]
[[File:Example.jpg|175px]]
</pre>

[[File:Example.jpg|220px]]
[[File:Example.jpg|100px]]
[[File:Example.jpg|150px]]
[[File:Example.jpg|250px]]
[[File:Example.jpg|200px]]
[[File:Example.jpg|50px]]
[[File:Example.jpg|220px]]
[[File:Example.jpg|175px]]

'''To wrap images of varying widths with captions''' it is necessary to use div HTML for an unordered list. Along with <code>style="display: inline-block;"</code>. For more info and ideas see: [http://www.sitepoint.com/give-floats-the-flick-in-css-layouts Give Floats the Flick in CSS Layouts].

<source lang="html">
<div><ul> 
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 1]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|100px|Caption 2]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|150px|Caption 3]] </li>

<translate>
<!--T:164-->
Some wiki farms do not have all gallery options (such as "widths").</translate>
<translate>
<!--T:165-->
Also, sometimes one wants varying widths for images in a row.</translate>
<translate>
<!--T:166-->
Outside of a gallery, or the div HTML, it is impossible to have individual captions for images in a row of images that will wrap to the browser width.</translate>
<translate>
<!--T:167-->
Try it and see. Nothing else using wikitext works correctly. Images will either overlap stuff on the right, or force a horizontal scroll bar. 

<!--T:168-->
Using a left float ("left") for some images, combined with "none" for some of the images, will not work consistently either, especially if there is also a right sidebar of images.</translate>
<translate>
<!--T:169-->
Weird things will occur.</translate>
<translate>
<!--T:170-->
At narrower browser or screen widths an image out of the row may appear far down the page after the end of the right sidebar of images.

== Link behavior == <!--T:171-->

<!--T:172-->
By default an image links to its file description page.</translate>
<translate>
<!--T:173-->
The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior.

<!--T:174-->
Alternatively, you can create a text link to a file description page or to the file itself.</translate>
<translate>
<!--T:204-->
See <tvar|1>{{ll|Help:Linking to files}}</>.

=== Display image, link it to another page or website === <!--T:180-->
</translate>
<!--{{note|link '''does not work with''' thumb '''or''' frame.}}
(@note above: link worked fine using thumb and frame)
(reply: thanks for pointing this out, must have been a bug fix)
(Note that MediaWiki v. 1.16 fails to link with 'frame' or 'thumb')
-->

<translate>
<!--T:181-->
Use "link=" option to link image to another page or website:

<!--T:182-->
Clicking on the below image will take you to [[MediaWiki]]:
</translate>

 <nowiki>[[</nowiki>File:Wiki.png|50px|link=MediaWiki]]

[[File:Wiki.png|50px|link=MediaWiki]]

<translate>
<!--T:183-->
Clicking on the below image will take you to ''example.com'':
</translate>

 <nowiki>[[</nowiki>File:Wiki.png|50px|link=http://example.com]]

[[File:Wiki.png|50px|link=http://example.com]]

<translate>
=== Display image, turn off link === <!--T:184-->

<!--T:185-->
Use "link=" option with no value assigned to turn link off entirely; the below image is not a link:
</translate>

 <nowiki>[[</nowiki>File:Wiki.png|50px|link=]]

[[File:Wiki.png|50px|link=]]

<translate>

== Requisites == <!--T:186-->

<!--T:187-->
Before using images in your page, the system administrator of your wiki must have [[<tvar|uploads>Special:MyLanguage/Manual:Configuring file uploads</>|enabled file uploads]] and a user has to [[<tvar|managing>Special:MyLanguage/Help:Managing files</>|upload the file]].</translate>
<translate>
<!--T:188-->
System administrators may also set the wiki to accept files from [[<tvar|image>Special:MyLanguage/Manual:Image Administration#Foreign Repositories</>|foreign repositories]], such as the [<tvar|url>http://commons.wikimedia.org/wiki/Main_Page</> Wikimedia Commons].</translate>
<translate>
<!--T:189-->
For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

== Files at other websites == <!--T:190--> 

<!--T:191-->
You can link to an external file available online using the same syntax used for linking to an external web page.</translate>
<translate>
<!--T:192-->
With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.
</translate>

<pre>[http://url.for/some/image.png]</pre>

<translate>
<!--T:193-->
Or with a different displayed text:
</translate>

<pre>[http://url.for/some/image.png <translate><!--T:195-->
link text here</translate>]</pre>

<translate>
<!--T:196-->
Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):
</translate>
<pre>[http://www.example.com/some/image.png <translate><!--T:197-->
Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.</translate>]</pre>
which renders as: [http://www.example.com/some/image.png <translate><!--T:198-->
Example '''<del>rich</del>''' ''<ins>link text<ins>'' here.</translate>]

<translate>
<!--T:199-->
If it is enabled on your wiki (see <tvar|AllowExternalImages>{{ll|Manual:$wgAllowExternalImages}}</>), you can also embed external images. To do that, simply insert the image's url:
</translate>
<pre>http://url.for/some/image.png</pre>
<translate>
<!--T:200-->
Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.

<!--T:201-->
If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.
