rsync image files?

[gateway2 at btopenworld.com]

I'd like to be able to use rsync to copy partition image files (see http://www.partimage.org) to another Linux box.  These files are each about 2gb in size, and I would like to only copy the differences.  I wondered if rsync's differencing would be able to chop out the differences and splice them into the destination files.

Any help greatly appreciated.
