Help:Images
Template:PD Help Page 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.
Syntax
The full syntax for displaying an image is:
[[File:{filename}|{options}]]
Where options can be zero or more of the following, separated by pipes:
border
,frame
,thumb
, orframeless
: Controls how the image is formattedleft
,right
,center
,none
: Controls the alignment of the image within a textbaseline
,sub
,super
,top
,text-top
,middle
,bottom
,text-bottom
: Controls the vertical alignment of the image within a text{width}px
: Resizes the image to the given width in pixels{width}x{height}px
: Resizes the image to fit within the given width and height in pixels; it is possible to specify only the height by writingx{height}px
link={destination}
: Allows to link to an arbitrary title, URL or just nowhere (1.14+)link=
: Will display an image without link, e.g.[[File:Name.jpg|link=]]
.- Note that
link
cannot be used in conjunction withthumb
orframe
.
alt={alternative text}
: For changing the alternative text (alt=""
) of an image (1.14+)- Special cases:
page=1
: 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 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.
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
.

Vertical alignment
text text [[File:MediaWiki:Image sample|20px]] text text [[File:MediaWiki:Image sample|20px|baseline]] text text [[File:MediaWiki:Image sample|20px|sub]] text text [[File:MediaWiki:Image sample|20px|super]] text text [[File:MediaWiki:Image sample|20px|text-top]] text text [[File:MediaWiki:Image sample|20px|middle]] text text [[File:MediaWiki:Image sample|20px|bottom]] text text [[File:MediaWiki:Image sample|20px|text-bottom]]
results in (the text is underlined to show the result more clearly)
text text [[File:MediaWiki:Image sample|20px]] text text [[File:MediaWiki:Image sample|20px|baseline]] text text [[File:MediaWiki:Image sample|20px|sub]] text text [[File:MediaWiki:Image sample|20px|super]] text text [[File:MediaWiki:Image sample|20px|text-top]] text text [[File:MediaWiki:Image sample|20px|middle]] text text [[File:MediaWiki:Image sample|20px|bottom]] text text [[File:MediaWiki:Image sample|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
border
ed, the size can be both reduced and enlarged. - A image with
frame
always ignores the size specification. - The size of an image with
thumb
andframeless
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.
Format | Reduced | Enlarged

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:{filename}|{caption} File:{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> File:MediaWiki:Image sample|Item 1 File:MediaWiki:Image sample|a link to [[Help:Contents]] File:MediaWiki:Image sample File:MediaWiki:Image sample File:MediaWiki:Image sample| ''italic caption'' File:MediaWiki:Image sample|on page "{{PAGENAME}}" </gallery>
is formatted as:
- Example.jpg
Item 1
- Example.jpg
a link to Help:Contents
- Example.jpg
- Example.jpg
- Example.jpg
italic caption
- Example.jpg
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.
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:MediaWiki:Image sample]] [[:File:MediaWiki:Image sample|Sunflowers]]
results in
[[:File:MediaWiki:Image sample]] [[:File:MediaWiki:Image sample|Sunflowers]]
Link directly to file
You can use the pseudo-namespace “Media” to link directly to a file, bypassing the description page.
[[Media:MediaWiki:Image sample]] [[Media:MediaWiki:Image sample|Sunflowers]]
results in
[[Media:MediaWiki:Image sample]] [[Media:MediaWiki:Image sample|Sunflowers]]
You can also use:
[[Special:FilePath/MediaWiki:Image sample]]
which can be used to link to a potential file, even if it doesn't exist. You can also use:
{{FILEPATH:MediaWiki:Image sample}}
which generates an external URL to the file inline:
Requisites
Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons.
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 Manual:$wgAllowExternalImages), you can also embed external images. To do that, simply insert the image's url:
http://url.for/some/image.png
