Would something like PIL's putalpha do what you want? (provided you *have* PIL)
http://www.pythonware.com/library/pil/handbook/image.htm (search for putalpha)

import Image
my_image = Image.open('somefile.jpg')
my_image.put_alpha(0)
my_image.save('somefile.png')

This would convert all the black (int val for black = 0) in your image
to alpha's, but then you'd have to save to something that supports an
alpha channel.
