I don't really have any odd markings..but I noticed you don't have any plain old socks, so here's a sock if it's any help at all!

And do white marks from ill fitting saddles count? I have some pretty good pictures of those unfortunately for the horse in them =(
I'll just toss him in there in case it's of any use.

That same horse also has a freeze brand on the other side, if you have any interest in putting types of brands up..

Anyway, enough of my desperate attempts to be as helpful as possible =P Good luck with the site! =)
