Also, I removed your map pics from my site after I read your post because I realized that that was a wrongdoing.
You can use them since they are not copyrighted material. Just please put a referance somewhere on the site that says where the animated gifs came from. Takes a lot of time to put them together and as far as I know they are unique. I don't mind people using them as long as credit is given. It is when someone copies them and presents them as their own that can be a little bit disheartening.
