How it works
A photo of a friend is not only yours, because it is theirs too. The person who pressed the button is not the only one with a say.
Ask before you post or forward a picture of a friend: where it will go, and who can see it.
You cannot see how they feel about it. A picture can be funny to you and upsetting to them.
If someone asks you to take a picture down, do it right away, and ask anyone with a copy to delete it.
