How to Change the Key Frame Photo of Live Photos on iPhone and iPad
Live Photos are the fun animated images captured by modern iPhone and iPad cameras. Essentially each Live Photo is a still image attached to a short movie clip, and much like movie clips there is a key image that can be set to represent the picture as a thumbnail. Changing that key photo can be desirable if the Live Photo thumbnail preview doesn’t really capture the image well, and you can instead scrub around in the Live Photo for a thumbnail that better represents the image.
This tutorial will show you how to change and set a Live Photo key frame photo in iOS, which will change both the thumbnail of the Live Photo as well as the picture you see when you browse to the Live Photo in the Photos app on iPhone and iPad.
