Custom picture/background for individual pages

Hi Sakin, maybe this has been asked before... just couldn't find a topic for it :( (webpage-address: www.wowow.eu [test-site]) I'd like to have an individual background(-picture) for certain pages within our website. I've found a plugins, which allows to change the browser-background for a page (i.e. "Custom Background Extended"), but not a way to JUST define/change the background of the page/article itself. To make it a bit more clear... If you go to [http://www.wowow.eu/?page_id=133], you'll find a browser-background of blue screws and a page/artikel-background, which is white. Is there a way to substitute the white with either a different color or even with a picture? If possible, is there a plugin to manage this?? Thanks in advance, cheers, Steve
