Help:Images

This page explains the image syntax when editing the wiki. Before using images in your page, your wiki must have file uploads enabled (see the for details) and you have to upload a file.

Syntax
The full syntax for displaying an image is: {options} Where options can be zero or more of the following, separated by pipes:
 * ,,  , or  : Controls how the image is formatted
 * ,,  ,  : Controls the alignment of the image within a text
 * ,,  ,  ,  ,  ,  ,  : Controls the vertical alignment of the image within a text
 * : Resizes the image to the given width in pixels
 * : Resizes the image to fit within the given width and height in pixels; it is possible to specify only the height by writing
 * : Allows to link to an arbitrary title, URL or just nowhere (1.14+)
 * : Will display an image without link, e.g..
 * Note that  cannot be used in conjunction with   or  .
 * : For changing the alternative text of an image (1.14+)
 * Special cases:
 * : Displays the specified page when showing a djvu file

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,  , and   and/or. 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.

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, which will try to adjust its size to more desirable size.

Note that by writing, you can use a different image for the thumbnail.

Alignment
Note that when using  or , the default alignment will be.

Vertical alignment
text text 20px text text 20px|baseline text text 20px|sub text text 20px|super text text 20px|text-top text text 20px|middle text text 20px|bottom text text 20px|text-bottom

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

text text 20px text text 20px|baseline text text 20px|sub text text 20px|super text text 20px|text-top text text 20px|middle text text 20px|bottom text text 20px|text-bottom

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


 * When the format is not specified, or only ed, the size can be both reduced and enlarged.
 * A image with  always ignores the size specification.
 * The size of an image with  and   can be reduced, but can not be enlarged beyond the original size of the image.

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

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

Parameters
The gallery tag itself takes several additional parameters:
 * : sets a caption on the gallery.
 * : sets the widths of the images.
 * : sets the (max) heights of the images.
 * : sets the number of images per row.

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

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

You can also use:

/

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

which generates an external URL to the file inline:

Web
You can link to an external file available online using the same syntax used for linking to an external web page.  Or with different text: link text here If it is enabled on your wiki (see ), you can also embed external images. To do that, simply insert the image's url: http://url.for/some/image.png

Local folder
You can set your wiki to use media files from a local folder, without needing to upload them into the wiki, through the $wgForeignFileRepos array. This is just a demonstration feature at present, and will probably be too slow for busy wikis or slow servers due to the lack of caching; however, it allows full usage of the image syntax described above, including captions and resizing options.

The below code enables media files from it:
