DokuWiki

Sometimes you may want to embed a dynamic image like this one

Using the usual method:

{{http://kalsey.com/tools/buttonmaker/button.php?barPosition=50&leftText=Dynamic&leftTextColor=ffffff&rightText=IMG&rightTextPosition=54}}

doesn't work:

button.php

This is because DokuWiki assumes an image ends with .gif,.jpg or .png but this file ends with .php. The trick is to append an additional CGI parameter like this: &.png – the CGI will ignore this unknown parameter but DokuWiki will think it's an image.

You also need to add a question mark at the very end or DokuWiki will think the CGI parameters are caching options.

For use of { or } in the image url these need to be URL-encoded as %7B and %7C (it clashes with the media link syntax otherwise)

Example of usage of the &.png? syntax:

{{http://kalsey.com/tools/buttonmaker/button.php?barPosition=50&leftText=Dynamic&leftTextColor=ffffff&rightText=IMG&rightTextPosition=54&.png?}}

It is sometimes necessary to remove a media file, which was being uploaded before. To do this the ACL feature needs to be enabled and the user who wants to delete files needs to have the DELETE permission. Files can be deleted with the garbage can icon then.

To link images to other resources, simply pipe that link into the image, as you would with any other text.

Example:

Example:  [[http://www.google.com|{{wiki:dokuwiki-128.png}}]]

If the image link is to local media (like a .pdf), you can use the following syntax:

Example:

 Example:   [[this>_media/wiki:dokuwiki-128.png|{{wiki:dokuwiki-128.png}}]]

To improve the performance for the user, DokuWiki tries to cache external images. If you want to use an external image without caching you can add the nocache parameter like this.

{{http://de3.php.net/images/php.gif?nocache}}

You can combine this parameter with resizing, too.

{{http://de3.php.net/images/php.gif?300x50&nocache}}

Hitting an external Server on every pageload isn't very polite. Instead you can use the parameter recache to let DokuWiki recache the image using the interval specified in the cachetime config option:

{{http://de3.php.net/images/php.gif?recache}}
