I've posted a simple ImageQt interface module for PIL and PyQt4 here:
http://svn.effbot.python-hosting.com/stuff/sandbox/pil/ImageQt.py
this interface handles 1, P, L, and RGB images efficiently. usage:
im = Image.open(...) # or some other pil operation
qim = ImageQt.toimage(im)
# to access the QImage, use qim.image. e.g:
label.setPixmap(QtGui.QPixmap.fromImage(qim.image))
note that the toimage() function returns a wrapper object, not a QImage
instance. I didn't find a reliable way to subclass from QImage, nor any
other way to attach custom attributes to an existing QImage object. if
anyone knows how to do that, let me know.
