{{PD Help Page}}

ここではウィキ上での'''画像'''表示のためのマークアップを説明しています。ページで使用するには通常、あなたまたは他の利用者が[[Help:Managing files|画像をアップロード]]する必要があります。

MediaWiki サーバーに格納されている画像は通常、MediaWiki リンクのターゲットとして名前空間接頭辞 <code>File:</code> を使用してレンダリングされます (以前の名前空間接頭辞 <code>Image:</code> にも別名として対応しています)。 別名の名前空間接頭辞 <code>Media:</code> も元のメディア ファイルのコンテンツを参照するのに有用です (あらゆる MediaWiki ページとは別個で描画またはダウンロードできるようにするため)。

ウィキメディアが使用しているその他の形式、およびその他の場所で広く有効になっている形式 (these may require extra set-up beyond what is enabled by default):

* .svg : scalable image in the ''Scalable Vector Graphics'' format (specified by the ''W3 Consortium''). See {{mediawiki|Manual:Image_Administration#SVG}}.

* .tiff : Tagged image format. Often used for high-resolution archival photographs. Often used with {{mediawiki|Extension:PagedTiffHandler}}.

* .ogg, .oga, .ogv : Ogg multimedia (audio or video). Not an image format, but treated similarly. Often used with {{mediawiki|Extension:OggHandler}}

* .pdf : multipaged documents in the ''Portable Document Format'' (initially specified by ''Adobe''). Often used in conjunction with {{mediawiki|Extension:PdfHandler}}

* .djvu : multipaged bitmap documents in the ''DejaVu'' format (most often, scans of books). See {{mediawiki|Manual:How to use DjVu with MediaWiki}}

オプションはまったく指定しなくてもよいし、複数指定することもできます。オプションはパイプ記号（<code>|</code>）で区切ります:

* ''[[#Altering the default link target|Link]] option'': one of

** '''link=''' (with an empty value) —  ({{mediawiki|rev:41727|MediaWiki 1.14 以降}}) Displays an image without any activable link; e.g. <code><nowiki>[[</nowiki>File:Example.jpg|20px|link=]]</code> renders as [[File:Example.jpg|20px|link=]].

* Other specific options:

** '''alt='''''{alternative text}'' — ({{mediawiki|rev:41837|MediaWiki 1.14 以降}}) 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).

** '''class='''''{html class}'' — (MediaWiki 1.20 以降) Defines classes (maps to the HTML attribute <code>class="..."</code> of the generated <code>&lt;img /&gt;</code> element).

** '''lang='''''{language code}'' — (MediaWiki 1.22 以降) 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.

If a parameter does not match any of the other possibilities, it is assumed to be the caption text. Caption text shows below the image in '''thumb''' and '''frame''' formats, or as tooltip text in any other format. Caption text displayed in the '''thumb''' and '''frame''' formats may contain wiki links and other formatting. MediaWiki extensions can add additional options.

{{Help:Images/frame|frame=border|ex='''border''' results in a very small gray border|float=no|inline=yes|render caption=no}}

{{Help:Images/frame|frame=thumb|ex='''thumb''' or '''thumbnail'''|float=yes|inline=no|render caption=yes}}

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). The alternative is to specify the desired maximum height (in pixels) explicitly.

=== 水平配置 ===

<code>frame</code> および <code>thumb</code> を使う時には、デフォルトの配置は <code>right</code> になります。

{{Help:Images/frame|2=100px|frame=right|ex=specify horizontal alignment as: '''right'''|inline=no|float=yes}}

=== 垂直配置 ===

The vertical alignment options take effect only if the image '''is''' rendered as an inline element and '''is not''' floating. 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.

Notes:

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). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).

The following table shows how to alter the link target (whose default is the image description page) or how to remove it. Changing the link does not alter the format described in the previous sections.

== 画像ギャラリーのレンダリング ==

<code><nowiki><gallery></nowiki></code>タグを使って、簡単にサムネイルのギャラリを作成できます。マークアップは次の通りです。

Captions are optional, and may contain wiki links or other formatting. 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). For example, with multi-paged media like pdfs, you can use code like <code>page=4</code>.

<nowiki><gallery></nowiki>

File:Example.jpg|<nowiki>[[Help:Contents]]</nowiki> へリンク

* <code>packed</code> causes images to have the same height but different widths, with little space between the images. The rows in this [[Wikipedia:Responsive web design|responsive]] mode organize themselves according to the width of the screen.  

For example:

<pre>

</pre>

Examples of the other modes:

* <code>widths={width}px</code>: sets the widths of the images, default 120px. ''Note the plural, width'''s'''''.

* <code>showfilename={anything}</code>: Show the filenames of the images in the individual captions for each image (1.17 以降).

* <code>mode={traditional|nolines|packed|packed-hover|packed-overlay}</code>: See section above (1.22 以降).

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

Example:

Result:

The only thing that works for a row of images with varying widths is not to use "thumb" or "left" or "none".  

[[File:Example.jpg|300px]]

[[File:Example.jpg|300px]]

Some wiki farms do not have all gallery options (such as "widths"). Also, sometimes one wants varying widths for images in a row. Outside of a gallery it is impossible to have individual captions for images in a row of images that will wrap to the browser width. Try it and see. Nothing works. Images will either overlap stuff on the right, or force a horizontal scroll bar.  

 

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. Weird things will occur. 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.  

If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width.  

== リンクの挙動 ==

By default an image links to its file description page. The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior. Alternatively, you can create a text link to an image's description page or to the image itself.

コロン (<code>:</code>) を <code>{{ns:image}}:</code> の前に追加すると、画像をページ内に埋め込む代わりに、ファイルの説明ページへリンクします。

[[:{{ns:image}}:{{mediawiki:image_sample}}]]

=== Text link to actual image ===

 

 

 

== その他のウェブサイトのファイル ==  

You can link to an external file available online using the same syntax used for linking to an external web page. With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.

If it is enabled on your wiki (see {{mediawiki|Manual:$wgAllowExternalImages}}), you can also embed external images. To do that, simply insert the image's url:
