Yay, random image works, thank you!!! But the image is too high up, it should be between the top row and the search box. You can see it here http://bit.ly/O55bWz . Do you know how to solve it? By default the site shows a logo with the name of the site, in this case Site-Test (temporary name). You couldn't get rid of it unless you replaced it with a new image, but I solved it by adding a transparent image there, so now you can't see it, otherwise it would have been 2 images there.
