iCloud: Shared Albums in iCloud
You can create Shared Albums and invite friends and family to post their own photos, videos, and comments. You can quickly and easily see the latest updates from all your shared albums in For You in Photos on your iOS device and in Shared Albums in Photos on your Mac, on iCloud.com, and on a Windows computer.
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 Shared Albums.)
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 View your shared Family album in iCloud.
Note: To prevent unintended or excessive use, Shared Albums limits the number of photos and videos that can be uploaded within given periods of time. See the Apple Support article My Photo Stream and Shared Albums limits.
