He told you it was a method of the image...

Another version of what you are doing uses a list comprehension
which might be slightly faster:

pixels = [image.getpixel((x,y)) for x in range(1024) for y in 
range(768)]

But your example didn't show you doing anything with the pixels you
retrieve, so just putting them in a list might not help!

HTH,
