That's not true. Subversion fully supports binary diffs. So if you have an 
uncompressed .bmp image and you changed one pixel, you'll get a very small 
diff stored. Of course, if your image is compressed or otherwise encoded in 
a "weird" way, the diff may be much more substantial. Maybe you're confusing 
Subversion with CVS where each version of a binary file is an entire copy.

Like I said, Subversion has good support for binary diffs. So do other version 
control systems like Monotone. RCE by the originator of RCS ( 
http://www.aicas.com/rce.html ) can handle binary diffs, but only operates on 
a single byte at a time. If you want to handle compressed or encoded data 
efficiently, you may need to implement domain-specific logic. Rational 
ClearCase may have such functionality, but I didn't have any experience with 
it, so I can't tell you.

I think what he meant was a way to view previous images or differences between 
various images by interfacing with Subversion.
