The aren't according to the python rules: if you import both PIL.Image and Image you get two distinct modules in sys.modules (that is, sys.modules['Image'] is not sys.modules['PIL.Image']). PIL isn't too large, adding it twice won't really be a problem but it would be nice to avoid this issue. Ronald
