If you want to do image cropping non-interactively (ie. using a script or someting) I would recommend that you use something like 'convert' that comes with the ImageMagick utilites. You can say something like convert original.jpg -crop <specificiation> output.jpg and you'll get what you want. If you want to interactively decide what piece you want to crop, I think it would be better to use a graphics editing program like the GIMP. If you're trying to implement a graphics editor in Python, I think it will be quite hard. Maybe if you can explain your requirements a little more, I might be able to help. I've used PIL a few years ago and have some memory of what it provides.
