[Zope] Adding image property to ZClass?

Is there a way to add an image property to a ZClass? I created a ZClass to allow users to create a personal profile. The ZClass maintains their user information (name, address, etc.). I would like them to also be able to upload ONE image for their picture. Is there a way to do this and only allow one image? Thanks in advance.
