This is, I think, one of the big problems with why ZClasses are somewhat 'weak' (this is probably not the right word)... because they are designed 'thru the web' they must be constrained under the usual Zope secuirty concepts. This means, unfortunatly, that you are restricted then in what your class methods can do to the class unless you provide the hooks in Python to do the meaty stuff, like assign instance attribute (or call methods that begin with '_', etc.).

I just re-read this and realized that instances do have attributes of a sort, properties of property sheets. Perhaps it would be easier to extend properties to be able to handle an image property. -Michel
