See Help:Copying for instructions.

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 technical manual for details) and you have to upload a file.

Description	You type	You get
Embed image (with alt text)	[[Image:Example.jpg|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]]	Sunflowers
Border (100 pixels) Results in a very small gray border	[[Image:Example-white-bg.jpg|border|100px]]
Frameless Like thumbnail, respect user preferences for image width but without border and no right float.	[[Image:Example.jpg|frameless]]

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, 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
• 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.

Frame

The following table shows the effect of all available frame types.

Size and Frame

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

Alignment

[[Image:Wiki.png|50px]] (no alignment specified, or default alignment) text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text
[[Image:Wiki.png|50px|none]] (specify alignment as none) none none none none none none none none none none none none none none none none none none none none	[[Image:Wiki.png|50px|center]] center center center center center center center center center center center center center center
[[Image:Wiki.png|50px|left]] left left left left left left left left left left left left left left left left left left left left left left left left left left left left left left	[[Image:Wiki.png|50px|right]] right right right right right right right right right right right right right right right right right right right right right right right right right right

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 [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 only, not other images, with the <gallery> tag. The syntax is:

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

is formatted as:

• 

  Item 1

• 

  a link to Help:Contents

• 
• 
• 

  italic caption

• 

  on page "Images"

Parameters

The gallery tag itself takes several additional parameters:

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

• caption={caption}: sets a caption on the gallery.
• widths={width}px: sets the widths of the images.
• heights={heights}px: sets the (max) heights of the images.
• perrow={integer}: sets the number of images per row.
