iCloud: iCloud Photo Sharing overview
iCloud Photo Sharing lets you share your favorite moments with just the people you choose. Friends and family can post their own photos, videos, and comments to your albums, and changes appear automatically on everyone’s devices. You can quickly and easily see the latest updates from all your shared albums in the Activity view on your device.
Note: Shared albums are called shared streams on iOS 7 devices.
How it works
Select photos and videos on your iOS device or computer.
Select a shared album you want to add to, or create a new one.
Invite people to subscribe to your album.
Your friends and family can use iCloud to view, like, and comment on your shared photos and videos from their iOS devices, Mac and Windows computers, or even Apple TV. (They can read but not add comments on Apple TV.)
Friends and family who don’t use iCloud can view your publicly shared albums on the web.
You and subscribers to your shared albums can add more photos and videos. (Subscribers need an iOS device, Mac, or Windows computer set up for iCloud Photo Sharing.)
Set up Family Sharing and it automatically sets up a family photo album on everyone’s devices, so you can share photos with the whole family. See the Apple Support article Family Sharing.
Note: To prevent unintended or excessive use, iCloud Photo Sharing limits the number of photos and videos that can be uploaded within given periods of time. For more information, see the Apple Support article My Photo Stream and iCloud Photo Sharing Limits.
