Instagram has introduced a new feature called Instants, and depending on how often you use the app's inbox, you may have already seen it without fully realising what it was. Some users have noticed a small photo tab appearing at the bottom-right corner of their Instagram DM screen. Tap on it, and you may find a collection of temporary photos shared by people you follow. That small addition is Instagram's latest experiment in fast, casual, and disappearing photo sharing.
