I'm trying to put a logo as a background picture in "About Us" page. The logo always shows as a picture and not as a background picture. Anyone tried to do that?
You have to set the background picture in your theme instead of your page. If it is only suposed to be active on one page, you can make a seperate template file, in the page edit screen you can set a different template per page.
There are other ways (custom field/component etc.), but this is the standard way I think.
