Thank you for all replying. I was playing around with them and realized that they are not in the same mode as the other things. They were in index mode instead of RGB mode. Once I change the mode I am able to resave them as JPEG's and then delete the GIF ones. Then I am able to move them into my layouts! It's funny though, I have a lot of other pictures that I have scanned into the computer and it's just these "older" (from the 1940's-50's) that this happened to. So, who knows. Maybe it has something to do with not having the original scanner hooked up anymore to the computer? Anyway, thank you again everyone for your replies.
