hi, thanx for the guidance and detailed replies..I tried to pack the r,g,b into a single value like below(something a member posted in the past) def rgbTopixelvalue((r,g,b)): alpha=255 return unpack("l", pack("BBBB", b, g, r, alpha))[0] if i apply this for all images i can represent each image as an array of longs instead of tuples.then for a pixel i can calculate the average value after this if i do the casting as you advised and create the avg image avgface = avgface.astype(numpy.uint8) here if i use these pixelvalues to create an imag img =Image.fromstring('RGB', (width, height), avgface.tostring()) it will fail because of -'not enough image data'..is there an alternative to create average rgb color image ?(i want to keep the rgb so can't convert to greyscale) is there something wrong with my approach? I am a newbie in PIL/ imageprocessing ..so i would greately appreciate feedback eric -- http://mail.python.org/mailman/listinfo/python-list
