It seems to save lots of simply one of many static photos which make up an animated gif. Like what you would see under windows image viewer when looking at an animated gif. But from what I’ve seen, the iPad will strip out the animations. Leaving you with just the first or final of the various photos which as soon as comprised the animation. Apple doesn’t allow the saving of gifs in Camera Roll for some cause. I started on Blackberry and Android before shifting to iOS and on Blackberry and Android you could save and consider gifs in your pictures.
