This pygtk faq looks promising: http://faq.pygtk.org/index.py?req=sh...=faq08.018.htp
I did some tests and I think it sort of works. Ran a test on the IDE. I need to retest on the IT and also do other tests...

I made a composite image of 2 png's but the other image was much smaller than the other so it appeared in the top left corner in the composite image.

Anyway I'm not sure how much this concerns the original question about the background of the home plugin.

And here is an example how to setup a window background:http://faq.pygtk.org/index.py?req=sh...=faq08.013.htp
Except that so far we have used frames.
