[Image-SIG] Deliver me from Kludgehood - PIL, filesystems and state

I have written the following abomination under windows2k:

I have written an embarassingly simple cgi script that cleans up old image
directories, grabs an image, performs (no) manipulation (as of yet),
creates a new directory for the image, writes the image and displays it. The
problems with this are many - if more than one person attempts to view the
page at once, then the earlier viewer will have a good chance of having his
pic wiped out before it can be displayed.

My question: is there a method to place an image in a page *without* writing
it to the filesystem, thus avoiding keeping state and the security risk of
allowing write access?

Thanks all!
