i'd like to find out how to extend the Image class in Zope to include a few more properties. Any pointers to documentation would be appreciated. There is a HowTo on "zope.org" on how to build product, something like "Product developpers guide".

Be careful to get the latest one. I have seen a post (-> searchable mailing list archive) with the URL for the various product documentation URL's. Dieter
