How can I stop sharing an album on Google Photos?
If you stop sharing an album:
To stop sharing:
Important Note: If someone has already downloaded or copied photos or videos they shared, deactivating sharing will not delete those downloads or copies.
Anyone who has the link to their shared album can view it automatically and add photos. You will see his profile picture in the upper left.
Important Notes: You cannot prevent individual people from adding items, but you can prevent everyone from adding items.
You will continue to see photos that other people added unless you delete them.
