OK, I started with a 320x240 image. Then using a background image(the one for the menu bar) that I had from a previous theme as a guide in photoshop i selected the entire image. That set the size that I wanted. I then dragged the selection boz over the the 320x240 image that I started with. You then move this selection to a new canvas the size that is appropriate. When saving you HAVE to sae it as a bitmap(I saved it as JPEG at first).
Here is a link to a post at Brighthand that the maker of ICBar posted. It helped me out a little bit so I thought you could use it.
