Hmm, yes, Image is actually deriving from Item_w__name__. The problem is
that Item_w__name__ has:

    def _setId(self, id):
        self.__name__=id

One way to fix your problem would be to subclass, in that order, from:
    OFS.CopySupport.CopySource
    OFS.Image.Image
    PortalContent
    DefaultDublinCoreImpl
because CopySource will expose the correct _setId.


BTW can someone enlighten us on the purpose of Item_w__name__ wrt Item?
