To do this, you need to go to the "My Photos" section, select the separate album and click on the gear under the album title, select "Edit photo album". You will be taken to the settings page where you can change the privacy or the name of the album.
We will immediately warn you that some albums — "Profile Photos", "Cover Photos" and "Photos on my page" will not be edited.
You can tag people on photos from your albums and from friends' albums. If the picture is there, open it and click on the "Mark person" button under the photo. It remains to select the desired area in the photo and specify the user name that you have as friends — those who are not, you will not be able to mark.
