This works for me for now. though I'm not having to read huge files 
currently.

zfile=zipfile.ZipFile("test.zip")
p=zfile.read("some.png")
img=QImage()
img.loadFromData(p, "PNG")
pixmap=QPixmap.fromImage(img)


Another way would be to load up data in a QByteArray and put it in 
QBuffer, but that still loads everything in memory, if you wanted to 
just stream some big file in a zip.

Just thought I'd followup.
