Discovered today if someone sends you a live photo and you have a IPhone 6 or 6 plus pressing and holding on the pic activates the photo. I'm not sure on the 4 or 5 models.
I just received one via mail. Thanks karenkcoulter..
Unfortunately I haven't been able to play the live photo in my 5s. I have saved the image to my photo album with no avail.. I guess it somehow is reduced to a regular photo in the process somewhere..
Live Photos can only be shared via iMessage, iCloud Photo Library, or AirDrop. In order to see them, the device has to be running iOS 9 or El Capitan.
If the photo was simply emailed, I don't believe it will work as a Live Photo.
