Yes, like queen_gina said "GifSoup.com" is great!! also photobucket is awesome!!

you have to convert it to make the scene repeat it..
It's not so difficult :) it's easy..
I think there are much more programs.. more expensive(which are not free like the one that I showed you).. those I didn't tried..
