I used GraphicsMagick for a similar situation. Once installed you can run `gm identify' to return all sorts of usefull information about the images. In my case I had python call 'gm' to identify the number of colors in each image, then inspect the output and handle the image accordingly. I'll bet PIL could do a similar thing, but in my case I was examining DPX files which PIL can't handle. Either approach will most likely take a bit of time unless you spread the work over several machines. ~Sean -- http://mail.python.org/mailman/listinfo/python-list
