Facebook is announcing that it’s begun introducing support for Live Photos in its app for the iPhone and iPad, allowing users of the iPhone 6s and 6s Plus to upload Live Photos from their devices. The feature will be available to just a small percentage of members at first, and will gradually roll out to more.
People who are included in the app rollout and who view those photos on an iPhone or iPad running iOS 9 will see the photos you shared as Live Photos. Everybody else—such as those with Android phones, Macs, or Windows PCs—will just see a conventional still picture and be none the wiser.
Facebook follows Tumblr as the second big network to add native support for Live Photos. If only there was also a social network where you could post pictures as quick updates and they could animate in a timeline. That would be nice, I guess.
