PD

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 {{ #ifeq:

 hergipedia.oc.uni-kiel.de

| www.mediawiki.org | technical manual | technical manual }} for details) and you have to upload a file.

Syntax

The full syntax for displaying an image is:

[[Datei:{filename}|{options}]]

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

• border, frame, thumb, or frameless: Controls how the image is formatted
• left, right, center, none: Controls the alignment of the image within a text
• baseline, 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 writing x{height}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 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.

Description	You type	You get

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.

Description	You type	You get

Vertical alignment

text text [[Datei:MediaWiki:Image sample|20px]]
text text [[Datei:MediaWiki:Image sample|20px|baseline]]
text text [[Datei:MediaWiki:Image sample|20px|sub]]
text text [[Datei:MediaWiki:Image sample|20px|super]]
text text [[Datei:MediaWiki:Image sample|20px|text-top]]
text text [[Datei:MediaWiki:Image sample|20px|middle]]
text text [[Datei:MediaWiki:Image sample|20px|bottom]]
text text [[Datei:MediaWiki:Image sample|20px|text-bottom]]

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

text text [[Datei:MediaWiki:Image sample|20px]] text text [[Datei:MediaWiki:Image sample|20px|baseline]] text text [[Datei:MediaWiki:Image sample|20px|sub]] text text [[Datei:MediaWiki:Image sample|20px|super]] text text [[Datei:MediaWiki:Image sample|20px|text-top]] text text [[Datei:MediaWiki:Image sample|20px|middle]] text text [[Datei:MediaWiki:Image sample|20px|bottom]] text text [[Datei: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 bordered, the size can be both reduced and enlarged.
• A image with frame always ignores the size specification.
• The size of an image with thumb and frameless 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>
Datei:{filename}|{caption}
Datei:{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>
Datei:MediaWiki:Image sample|Item 1
Datei:MediaWiki:Image sample|a link to [[Help:Contents]]
Datei:MediaWiki:Image sample
Datei:MediaWiki:Image sample
Datei:MediaWiki:Image sample| ''italic caption''
Datei: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.

Link to description page

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

[[:Datei:MediaWiki:Image sample]]
[[:Datei:MediaWiki:Image sample|Sunflowers]]

results in

[[:Datei:MediaWiki:Image sample]] [[:Datei:MediaWiki:Image sample|Sunflowers]]

Link directly to file

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

[[Medium:MediaWiki:Image sample]]
[[Medium:MediaWiki:Image sample|Sunflowers]]

results in

[[Medium:MediaWiki:Image sample]] [[Medium:MediaWiki:Image sample|Sunflowers]]

Files at other websites

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:

 hergipedia.oc.uni-kiel.de

| www.mediawiki.org | 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
