I can't see what's wrong offhand.
CMFDefault.Image works ok.
You should derive from CMFDefault.Image only (and don't call other
classes' __init__, that's not clean, call
CMFDefault.Image.Image.__init__). Start with a minimal empty class
sublcassing Image that just renames the class. Test that it works. Then
add one by one your methods and test at each step.
BTW when you say "errors", be precise. And if there's a traceback,
include it.
