Typically you would upload an image file to the wiki (See Help:Managing files) ...before you use the following wiki text to place the image on an article:

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

[[Image:Example.jpg|Sunflowers]]

Sunflowers

Link to description page

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

Image:Example.jpg
Sunflowers

Link directly to file

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

Media:Example.jpg
Sunflowers

Thumbnail
(centered, 100 pixels
wide, with caption)

[[Image:Example.jpg|center|thumb|100px|Sunflowers]]

(thumbnail)
Sunflowers
Border
(100 pixels)
Results in a very small gray border

[[Image:Wiki.png|border|100px]]

Wiki.png

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

Syntax

The full syntax for displaying an image is:

[[Image:{name}|{options}]]

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

  • thumb, thumbnail, or frame: Controls how the image is formatted
  • left, right, center, none: Controls the alignment of the image on the page
  • {width}px: Resizes the image to the given width in pixels
  • {caption text}
  • Special cases:
    • page=1: displays the specified page when showing a djvu file.

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 $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:

<gallery>
Image:{filename}|{caption}
Image:{filename}|{caption}
{...}
</gallery>

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

for example:

<gallery>
Image:Example.jpg|Item 1
Image:Example.jpg|a link to [[Help:Contents]]
Image:Example.jpg
Image:Example.jpg
Image:Example.jpg|''italic caption''
</gallery>

is formatted as:
