[Zope] Zope & Postgres with Images

I am trying to develope a db application that uses a postgres backend. 1) I want to store images in postgres db. Anyone figured how to do this? (Postgres does not have a built in type such as BLOB in mysql to store binary data) 2) Assuming that I have one figured out....how next do I render the images extracted from the db to a webpage through zope? thanks in advance karl Munroe
