use YouTube video as a GIF

It works for the long name YouTube video.
Add after “www.” and before “youtube.com” gif
So, for example, you’d turn:
www.youtube.com/watch?=BQwhOfAxrjU
into:
www.gifyoutube.com/watch?=BQwhOfAxrjU
Also the url without www. seems to work:
gifyoutube.com/watch?=BQwhOfAxrjU
http://www.gifyoutube.com/watch?=BQwhOfAxrjU
