In the meantime, as a workaround, I've created a small extension module which
will extract the image data from a QImage to a Python string:

http://www.boddie.org.uk/david/Projects/Python/Qt/Software/qimage-0.01.tar.gz

The example script included (main.py) will load an image using a QImage
object and save it using the Python Imaging Library. The example won't work
if you don't have the PIL, but it's not used by the actual module.

I hope it's useful to Tom, anyway!
