A few quick picks below in case you're in a hurry - otherwise navigation is on the top left.
Click the thumbnail to see the actual (large) animation. Save and use the large animation - not the thumbnails - on your phone! They'll resize to fit and look much crisper than a blurry thumbnail.To use - save the animation to your phone like you would any other image, and then send it in a text the same way you would any photo you saved. Please note that you need to save it - copy and paste won't work.
