It may not be as pretty as a parseable param array, but what about
just having all your args in a single JSON string. Are your template
authors savvy enough?

I'm a bit confused on a few points here. The upload_to field
attribute should be atomic to the imagefield - it doesn't rely on
related models.
your change_upload_to creates a new screenshot - but doesn't connect
