This page explains the image syntax when editing the wiki. Before using images, you have to upload a file.

Description You type You get
Embed image
(with alt text)



Link to description page



Link directly to file



(centered, 100 pixels
wide, with caption)

Results in a very small gray border



Like thumbnail, respect user preferences for image width but without border and no right float.

The full syntax for displaying an image is:


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

  • thumb, thumbnail, frame, or frameless: Controls how the image is formatted
  • left, right, center, none: Controls the alignment of the image on the page
  • baseline, sub, super, top, text-top, middle, bottom, text-bottom: Controls the vertical alignment of the image on the page
  • {width}px: Resizes the image to the given width in pixels
  • {caption text}: Must not end with "px"
  • Special cases:
    • page=1: Displays the specified page when showing a djvu file
  • link={destination}: Allows to link to an arbitrary title, URL or just nowhere (1.14+)
  • alt={alternative text}: For changing the alternative text (alt="") of an image (1.14+)

The options can be given in any order. 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.

Other files

You can link to an external file 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 {{ #ifeq:

| | Manual:$wgAllowExternalImages | Manual:$wgAllowExternalImages }}), you can also embed external images. To do that, simply insert the image's url:

  • http://url.for/some/image.png

Gallery of images

It's easy to make a gallery of thumbnails with the <gallery> tag. The syntax is:


Captions are optional, and may contain wiki links or other formatting.

for example:

Image:Binomial_Cube.jpg|Item 1
Image:Binomial_Cube.jpg|a link to [[Help:Contents]]
Image:Binomial_Cube.jpg|''italic caption''
Image:Binomial_Cube.jpg|on page "{{PAGENAME}}"

is formatted as:
