So I don't want to cheat someone out of a credit, if I'm unsure, do I just say "Paper not mine, lost the information" or something? I don't want to come off like I'm trying to take credit for someone else's work, ya know?

And I don't use Picasa because I keep my files all stored on a server, and Picasa won't pick up the network places, they have to be on my PC and I'm trying to conserve space on my local hard drive
