[Zope-dev] Access Zope objects from python

Hi This question is from a Zope newbie, who gets a little confused when trying to write a product for Zope. My product fetches a lot of picture information, and this information shall be viewed in a fotogallery (the viewer is made as a ZPT) My question is really simple then: When I write this product in python, how could I generate a zope image object of each of the pictures in the db. The part I am interested in is how I can access and create zope objects from python. Which classes do I have to inherit from? -Tor Oskar Wilhelmsen
