If I get this right, you're saving the original file, and a separate thumb file. While this seems interesting, it's not what I want to implement. It's more of a bit of catching the incoming data and transforming it before it gets saved in the model instance. On djangosnippets I've seen a thumbnail function able to work on provided data rather than a provided file path. This might be just what I need :) But since, I'm very new, I'm having hard times when something doesn't work. Debugging is an art of it's own :)
