I know how to change the background image for each page as a Page Attribute but I have a website with a fixed width, fixed height style and the main background image is contained within a Div tag called wrapper. The <div id=wrapper> is called from the header file. I want to be able to add a page attribute to allow the client to be able to select from a range of four images to be used as the background for that div. I have the four images loaded into a file set called background images.

Can someone point me in the right direction for the PHP to be able to vary the background URL for this div and have it available as a Page Attribute

Thanks in advance
