Would something like PIL's putalpha do what you want? (provided you *have* PIL)
Yes, I have PIL.
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.

Well, I want to set the alpha value for every pixel. So, every pixel, regardless of its color should be 50% transparent. The code I posted does that, but it doesn't save that alpha data to the file.
