Not really. Stuffit has a JPEG compressor which takes advantage of the fact that the JPEG algorithm isn't as optimal as it can be. It converts JPEG images to its own more compact representation which then can be converted back to JPEG as needed, without any loss. It is sadly not free. -- http://mail.python.org/mailman/listinfo/python-list
