This page explains the image syntax when editing the wiki. You or another user must usually upload an image before you can use it on a page. Images that are stored on a MediaWiki server are usually rendered by using the RequisitesBefore using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.). Supported media types for imagesThe following file formats are supported by default:
Other formats used on Wikimedia, and commonly enabled elsewhere (these may require extra set-up beyond what is enabled by default):
Other media types may be supported, but it may not be possible to display them inline. Rendering a single imageSyntaxThe full syntax for displaying an image is: [[File:filename.extension|options|caption]] where options can be empty or containing one or more of the following lower-case words, separated by pipes (|):
If a parameter does not match any of the other possibilities, it is assumed to be the caption text. If more than one non-parameter string is present, the final non-parameter string will be used as the caption. 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. If 'alt' is not specified and a caption is provided, the alternative text will be created automatically from the caption, stripped of formatting, except when in thumb or frame mode since the caption is already readable by screen readers in that case. Thumbnail sizesFile thumbnails are stored in discrete sizes. If a page specifies a thumbnail size that's not among the common thumbnail sizes (20px, 40px, 60px, 120px, 250px, 330px, 500px, 960px, 1280px, 1920px, 3840px), then MediaWiki will pick the closest larger thumbnail size but will tell the browser to downscale it to the requested size. In these cases, nothing will change visually but users might load slightly larger images. If it doesn't matter which thumbnail size is used in a page, please pick one of the standard sizes to avoid the extra in-browser down-scaling step. FormatThe following table shows the effect of all available formats. 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 Note that by writing Size and frameAmong different formats, the effect of the size parameter may be different, as shown below.
Horizontal alignmentNote that when using the Vertical alignmentThe 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. 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.

Stopping the text flowOn occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image.
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, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect.
The text flow can be stopped by placing All images rendered as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed 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 centered images). Altering the default link targetThe 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.
Rendering a gallery of imagesGallery syntaxIt's easy to make a gallery of thumbnails with the <gallery> File:file_name.ext|caption|alt=alt language File:file_name.ext|caption|alt=alt language {...} </gallery> Note that the image code is not enclosed in brackets when enclosed in gallery tags. Captions are optional, and may contain wiki links or other formatting. The words "center", "left", and "right" used as captions cause false-positive Linter errors. See T275074 for details.
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 The If the image links to an external site, the caption must come before the link parameter or the caption will not render. For example: <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'' File:Example.jpg|link=https://example.com|This text will not render because an external link came first File:Example.jpg|Links to external website|link=https://example.com File:Example.jpg|link=w:Main_Page|Internal link Example.jpg|on page "{{PAGENAME}}" File:Using Firefox.pdf|page=72 </gallery> is formatted as:

Examples of the other modes:
Optional gallery attributesThe gallery tag itself takes several additional parameters, specified as attribute name-value pairs: <gallery {parameters}> {images} </gallery>
In packed (and related) modes, the widths parameter has no effect; instead, the heights parameter determines the minimum height of the images. Packed modes adjust the width of images to ensure that each row is of equal length, except when a row contains too few images to achieve this without excessively enlarging the images.

Row of images that will wrap to browser widthOne way that works for a row of images with varying widths is not to use "thumb" or "left" or "none". If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width. If necessary, narrow the browser window to see the images wrap to the next row. [[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 <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> <li style="display: inline-block;"> [[File:Example.jpg|thumb|none|250px|Caption 4]] </li> <li style="display: inline-block;"> [[File:Example.jpg|thumb|none|200px|Caption 5]] </li> <li style="display: inline-block;"> [[File:Example.jpg|thumb|none|50px|Caption 6]] </li> <li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 7]] </li> <li style="display: inline-block;"> [[File:Example.jpg|thumb|none|175px|Caption 8]] </li> </ul></div> To align the top edge of images add the vertical-align command <div><ul> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|220px|Caption 1]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|100px|Caption 2]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|150px|Caption 3]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|250px|Caption 4]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|200px|Caption 5]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|50px|Caption 6]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|220px|Caption 7]] </li> <li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|175px|Caption 8]] </li> </ul></div> 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, 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. Try it and see. Nothing else using wikitext works correctly. 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. Link behaviorBy 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 a file description page or to the file itself. See Help:Linking to files . Display image, link it to another page or websiteUse the "link=" option to link an image to another page or website: Clicking on the below image will take you to MediaWiki: [[File:MediaWiki-2020-logo.svg|50px|link=MediaWiki]] Clicking on the below image will take you to example.com: [[File:MediaWiki-2020-logo.svg|50px|link=http://example.com]] Display image, turn off linkUse the "link=" option with no value assigned to turn the link off entirely; the below image is not a link: [[File:MediaWiki-2020-logo.svg|50px|link=]]
Link to an imageAdd [[:File:MediaWiki-2020-logo.svg]] [[:File:MediaWiki-2020-logo.svg|Wiki]] Directly linking to an imageThe above examples link to the image's description page.
To directly link to an image, the pseudo-namespace [[Media:MediaWiki-2020-logo.svg]]
Direct links from external sitesAnother possibility is to use the Special:Redirect/file page (or its alias Special:Filepath). Unlike the above example, you can link to it from external websites as well as from MediaWiki pages. [[Special:Redirect/file/Wikipedia.png]] The parameters https://www.mediawiki.org/w/index.php?title=Special:Redirect/file/Wikipedia.png&width=100&height=100
Obtaining the full URL of an imageTo obtain the full path of an image (without going through redirects as shown above), some Magic words can be used. {{filepath:MediaWiki-2020-logo.svg}}
Becomes:
In the event that this is used from a template where the {{filepath:{{PAGENAME:File:MediaWiki-2020-logo.svg}}}}
Becomes:
Files at other websitesYou 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. [http://url.for/some/image.png] Or with a different displayed text: [http://url.for/some/image.png link text here] Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (except for embedded links that would break the surrounding link): [http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.] which renders as: Example If it is enabled on your wiki (see Manual:$wgAllowExternalImages ), you can also embed external images. To do that, simply insert the image's URL: http://url.for/some/image.png Embedded images can be resized by the CSS If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above, unless the site's Manual:$wgAllowExternalImagesFrom has a value. It is also possible to use InstantCommons or other shared file repositories to load files from other wikis, which are treated as if they were local images. See also
