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.

Contents

Syntax

The full syntax for displaying an image is:

 [[File:{file_name}|{options}]]

Where options can be zero or more of the following, separated by pipes:

The options can be given in any order. If the given options conflict each other, the latter is applied, except for the format options, where the options take the priority in the order of frame, thumb, and frameless and/or border.

If a given option does not match any of the other possibilities, it is assumed to be the caption text. Caption text can contain wiki links or other formatting. If no caption text is supplied a caption is automatically created showing the file name; to completely remove the caption, set it to <span title=""></span>. For example, [[File:Example.jpg|20px|<span title=""></span>]].

Format

The following table shows the effect of all available formats.

When the height of an image in thumbnail is bigger than its width and you find it too outstanding, you may try the option upright, which will try to adjust its size to more desirable size.

Note that by writing thumb={filename}, you can use a different image for the thumbnail.

Alignment

Note that when using frame or thumb, the default alignment will be right.

Description You type You get

Vertical alignment

text text [[File:Example.jpg|20px]]
text text [[File:Example.jpg|20px|baseline]]
text text [[File:Example.jpg|20px|sub]]
text text [[File:Example.jpg|20px|super]]
text text [[File:Example.jpg|20px|text-top]]
text text [[File:Example.jpg|20px|middle]]
text text [[File:Example.jpg|20px|bottom]]
text text [[File:Example.jpg|20px|text-bottom]]

results in (the text is underlined to show the result more clearly)

text text Example.jpg text text Example.jpg text text Example.jpg text text Example.jpg text text Example.jpg text text Example.jpg text text Example.jpg text text Example.jpg

Size and Frame

Among different formats, the effect of the size parameter may be different, as shown below.

For how it appears when its size is not specified, see Format section above.

Stopping text flow

On occasion it is desirable to stop text from flowing around an 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 <br style="clear: both" /> before the text that should start after the image.

Gallery of images

It's easy to make a gallery of thumbnails only, not other images, with the <gallery> tag. The syntax is:

<gallery>
File:Image Name.ext|caption
File:Image Name.ext|caption
{...}
</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.

for example:

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg
File:Example.jpg| ''italic caption''
File:Example.jpg|on page "{{PAGENAME}}"
</gallery>

is formatted as:

Parameters

The gallery tag itself takes several additional parameters:

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

Example:

Coding:

<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
</gallery>

Result:

Links

Link to description page

If you put a colon (:) before File:, the image will not be embedded and the link will lead to the description page of the file.

[[:File:Example.jpg]]
[[:File:Example.jpg|Sunflowers]]

results in

File:Example.jpg Sunflowers

Link to another page

This will make a 50px width picture with a link to the page MediaWiki:

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

50px

Link directly to file

You can use the pseudo-namespace “Media” to link directly to a file, bypassing the description page.

[[Media:Example.jpg]]
[[Media:Example.jpg|Sunflowers]]

results in

Media:Example.jpg Sunflowers

You can also use: 

[[Special:FilePath/Example.jpg]]

which can be used to link to a potential file, even if it doesn't exist. You can also use:

{{FILEPATH:Example.jpg}}

which generates an external URL to the file inline: http://wiki.contextgarden.net/images/a/a9/Example.jpg

Requisites

Before using images in your page, the system administrator of your wiki must have Template:mediawiki and a user has to upload the file. System administrators may also set the wiki to accept files from Template:mediawiki, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Files at other websites

You can link to an external file available online using the same syntax used for linking to an external web page.

[http://url.for/some/image.png]

Or with different text:

[http://url.for/some/image.png link text here]

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

http://url.for/some/image.png
