Then I will have to subclass from OFS.Image.File and I was told that this is somehow evil. From a previous thread:

This makes the code in the ZPT all messy...

The third option is to somehow construct the the object the method should operate on from self.REQUEST.

I was really hoping to get to understand this acquisition thing.
Am I really that far away from getting it? What does it take to grasp it?

Thanks anyway for your time and efforts!
