At the moment, I think I need to read through it a couple more times, but
it seems rather perverse to be using os.path.join() and then using
os-specific filename separators, when the whole point of os.path.join() is
to not have to do that. (And then you do string cats for foto_path, instead
of using os.path.join() there.)
Where is upload_pic defined? Why does outfile's assignment have '(' and
')'? You want it to be a one-tuple? Ditto thumbnail_filename?
When you create thumbpath, why do you append thumbfile to the path you've
assembled with os.path.join() instead of including it in the args?
