Thank you for your reply.
I understand your third point. In this application though I have a many
images to a single detail structure.
For your first point "use `related_name` in your model fields to get pretty
backref names (so you don't have to use image_set everywhere)", how do I do
that and maintain the ability to reference the data via the two-fold nested
loop I need in my HTML template?
Thanks,
Tom
