> OMG, I'm so stupid and blind - I've clicked this URL xD . It got me as well ^_^ But to be on the topic. i don't know if this is possible and if it is than it might be by accident so it might not be working well. i can't imagine that the GDM (i assume you where talking about GDM) developers have thought of someone putting in the URL to a image for the background ^_^
