With Shared Albums in the Photos app on iOS 15 and iPadOS 15,, you can share photos and videos with any folks you choose. And they can add their own photos, videos, and comments. Shared Albums works with or without iCloud Photos and My Photo Stream.
To turn on Shared Albums
Go to Settings > [your name] > iCloud > Photos, then turn on Shared Albums.
To create a new shared album
- Tap Albums, tap the “+“ icon, then tap New Shared Album.
- Give the album a name, then tap Next.
- Choose people to invite, or type an email address or phone number, then tap Create.
To turn on public viewing in iCloud
- Tap Albums, then select a shared album.

When Public Website is turned on, anyone with the iCloud URL can view the album.
To Add photos and videos to a shared album
- Tap Albums, select a shared album, then tap the “+” sign.

Subscribers can add photos and videos to the album. Turn off the Subscribers Can Post button so only you can add photos and videos.

Rename a shared album

- Tap Edit, then tap the name of the album and enter a new one.
Subscribe to a shared album
When you receive an invitation, tap the iCloud icon (which looks, like, well, a cloud), then tap Accept. You can also accept an invitation in an email.
