Invite people to view your shared albums in iCloud
Sharing an album is an easy way to share just the photos and videos you want with just the people you choose. They can view, like, and comment on your photos and videos, and they can download your photos. They can also add their own photos and videos to your album using an iOS device, iPadOS device, Mac, or Windows computer.

Click the Share button
in the toolbar, click Shared Albums, then click New Shared Album.Type a name for the shared album, then type the email addresses of the people you want to share the album with.
If you want subscribers to be able to view the shared album from an iOS or iPadOS device, be sure to use the email addresses associated with their accounts.
Click Create.
