I shared a photo with my friends only. I'd like a friend of a friend to see a photo or a photoset. (He is not my friend.)
To do that, I set my photo with friends-only privacy and tag a friend of my friend. Curiously, it does not work for everybody. Indeed, usually I can reach such people in the list. How can fix it?
I know another way to make it work is to ask my friend to tag his friend on my photo, but I'd like to do it directly.
