Try
http://www.oldversion.com .com for previous version's that allow these search term's
Version 5.2.5.3 work's fine for default image filename searching.
There are quite alot of other p2p app's out there that allow searching on the Gnutella & Gnutella2 network's, but I always seem to end up reverting back to Bearshare because the interface is very user friendly.
Hope this help's.
Good luck with your finding
