>I am looking for put a background image on a popup menu and have it show in the background for each bar. Is this possible? If so, please help.

This is not possible out of the box.

If I had to do it, I'd go for using the windows API to find the windows handle of the popup window and see whether I could apply some Windows messages to draw on the window directly. I think it should be possible, but most likely very, very difficult and a vast knowledge of windows API drawing required.
