Body background pictures

Sorry folks... I posted this in the wrong forum.. should have been in the template forum.

Hi folks....
apologies if this is a stupid question, but how do I have a different main body background image (not the flashes-menu images) for the different top menu items.

have a look at www.black-bone.com , where "Home" shows one picture, and "Band" shown a different one (blue in this case).

regards all,
Mike

Use different modules for different pages (menu assignment) to show same menu, so create few flashes menu modules connect then to same menu , and set which one will appear on some page by using menu assignment in module settings.
