I am sure you would have already explored open source solution but LZMA is one of the best in compressing the files to a greater extent. Try the Java library for 7zip in the below link.

You need to compress the images individually more than they are already (which can reduce quality) Trying to compress images with a general lossless compression program won't be very successful as the data is compressed already.
