Does your script use any attributes from the photo object? any at all?
if so, all of its attributes are loaded into memory.

Im not sure how the photo product works, but if the photo data is
stored as an attribute of the *same* object then this explains the
memory growth.

The best way to avoid this problem is to store the photo metadata in a
separate persistent object from the bulk data, allowing the metadata
to be loaded into memory separately from the bulk data.

Ive not looked at the photo product, but it possibly could (and
probably should) be doing this itself anyway.

If thats not how the Photo product works, you could create your own
folderish object for storing your photo metadata. Lets call it a
PhotoFrame. Each PhotoFrame then contains a single Photo instance.

I hope that helps
