is this faster btw? I guess big doesn't help, it's only retrieved once
anyway? But is rows retrieved in every loop? the python interpreter
aint too smart?

you'd probably get more done if you read the replies you get a bit more
carefully. Robert Kern suggesting using numpy.asarray earlier:
def getPixels(fileName):
im = PIL.Image.open(fileName)
return numpy.asarray(im)
if you want to work with pixels on the Python level, use im.getdata() or
the pixel access object returned by im.load().
