I've read around here that you can't just put in a background image, you have to somehow incorporate your icons into the background.
I'm curious about this myself, but I don't even know where to begin a project like that.
If you want a sample of what I'm talking about...go to the themes section and download one..then open up the folder and you'll notice that the icons have a section of an image in their background.
I hope I didn't confuse you....
