Viewing portrait names with pics

[Desicardo]

Is there an easy way (program or method) to view thumnails of the portrait pack with the file names together?  Somehow the portrait for my Sorcerer Justin "Hanibal" Case changed mysteriously a couple weeks ago to the portrait that is next to it in the selection menu.  I need the name of the original portrait to have it changed back but it would take hours and hours to go through all the portraits listed one by one to find the original portrait.  
Thanks

I've had to do this before on a server I use to play on.  It didn't take as long as I thought it would.  Just use a good app like http://www.irfanview.com/ to quickly scan your portraits.  Just open the first file in your portrait folder, then keep the right arrow pressed until you see your portrait.
