What's the problem? Just organize them

IMO, this is a big decision, how to proceed? I would suggest that you get a copy of "The DAM book" by Peter Krogh
http://www.amazon.com/s/?ie=UTF8&key...l_568rhvijmy_e Tons of info for you to check out and you can decide how you would like to proceed! Keywords? Folders? etc, etc? I am not using keywords as of yet. I'm using folders by species for flora and fauna. For USA scenics, I'm creating folders for states then subfolders for counties. Much more can be done from there!

Good luck!
