NEW YORK -- The latest iPhones come with the ability to turn still images into video, but sharing has been limited to other Apple apps.

That's changing as Facebook, one of the leading forums for photo sharing, adds Apple's Live Photos feature to Facebook's iPhone and iPad app. Facebook will start offering it Monday to a limited number of users initially. A broader rollout is planned in the coming weeks. Facebook's support follows a similar move by Yahoo's Tumblr service.

With Live Photos on the iPhone 6s and 6s Plus, every still shot is accompanied by a three-second video, with sound. Apple is making tools available for third parties to incorporate the feature. The iPhone 6s models are required for creating Live Photos, but viewing can also be done on older devices.
