Wait a tick.
Why do you actually need PIL? Why not just directly store into the GridFS?
If you need image manipulation, then you have no choice but to use PIL's
handling.
You could do something like this:
img = Image.fromstring(f.read())
<do things that needed to be done>
write_image_into_database_thingy(img.tostring("jpeg")) #I think, that this
should be enough.
That's about it.
The upload part will give you tmp_file, whether you like it or not,
anyways. That's how uploads work.
