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.

        Maybe you've wanted Image.frombuffer() or Image.fromstring()?

    I tried, but to "convert" a File Object to an Image - File Object i
    read to use Image.open(file).

    I dont want to use tmp_file or write it to disk, because i use
    GridFS to store Files.

                    What is 'f'? Is it image data or the filename?
