Yes, like queen_gina alisema "GifSoup.com" is great!! also photobucket is awesome!!
I tried to make some of them too.. but I could make only small ones..
if wewe want to make them, wewe have to use "windows movie maker" which wewe have it already in your pc.
cut the scene.. make it short and then wewe have to convert that short video in a gif with this program:
link wewe have to convert it to make the scene repeat it..
It's not so difficult :) it's easy..
I think there are much zaidi programs.. zaidi expensive(which are not free like the one that I showed you).. those I didn't tried..
