changing the Background image in iChat windows?

By now, we’ve all seen the script that changes our ichat icon to be the current cover art, but I want more!

Since I have that same script running anyway, while it’s updating my ichat icon, I’d like to pull the images out of the other chat documents and place it as the background of any active chat windows.

The only thing I can’t figure out how to do is tell iChat to change that background via applescript. The iChat dictionary doesn’t have a way, and even the UI Element Inspector doesn’t show any image elements.

Does anybody know of a way to do this? I’ll share the finished script if I can get it to go!
