On iOS, however, users have Apple's image-management solutions and iCloud, so Google Photos is not on everyone's mind there. If you use it with an iPhone, however, or have just moved to iOS from Android, you'd be delighted to hear that Google updated its Photos app on Apple's venerable mobile OS to work with AirPlay. Yes, you can now stream photos and video to Apple TV via AirPlay, if you so desire, which is a welcome feat.
The app is a hefty 165 MB download from the source link below, but it gives you copious amount of free space to store your media, and now with AirPlay streaming you can display them easily on the biggest screen in the house. Sweet.
