[Zope] Adding image property to ZClass?

Not as a property, but as content:

  Make your ZClass an ObjectManager (use this as a BaseClass).
  Then, you can use "manage_addImage" to add an image to it.

You give your ZClass your own method to upload the image.
This method can check whether there is already an image:

     <dtml-if "_.hasattr(aq_explicit,'my_image')">
       <!-- already there -->
