You can use cStringIO to create an in-memory file handle, save to it from
PIL as normal, then store the contents of getvalue() in datastore. I just
completed a project that uses this method, and it works pretty well.
Side note, I've been storing the file base64 encoded as well, but I don't
know if that's strictly necessary.
