He is using a background image in one of the div containers.

There are two options to do that:

1. Overwrite the skin's CSS files and add your image there he way you want it to be. This is not recommended as it will break after a MediaWiki upgrade. (I guess this is the way the fahrrad wiki guys went anyway.)

2. Add according CSS styles to the wiki page MediaWiki:Vector.css in your wiki and upload the file somewhere on you server, e.g. in the images/ folder.
