what made you think you could write that? ;-)

the only way to create new images in PIL is to use
a factory function; the two most commonly used
functions are Image.open and Image.new.

see the docs for more info:
http://www.pythonware.com/library/pil/handbook/image.htm

pass it do a Python function?  sure.  like,
say:

    def procedure(im):
        im.save("out.jpg")

    procedure(Image.open("in.ppm"))
