What privacy setting on facebook changed here?

[Big Boy]

I have a "friend" who is not my facebook friend. She is what facebook calls a "friend of friend".
Her privacy settings used to be not to show anything except her profile picture, her name, her sex and her friends list.
Recently, it changed, and her photos tab is now visible on her profile, even though when clicking it, you get an empty screen and you can access no photo album at all.
What privacy setting did she change?

I know it is not facebook that did this because other "friends of friends" still have their photos tab invisible and others have always had it visible. I'm just wondering what privacy setting you can change to make your photo tab visible but not the albums themselves.

Thanks in advance!
Enabling "Posts by me" for Friends of Friends and disabling everything else can give this effect, but there's one problem: this will also show the wall, which then has messages like "x became friends with y", and "x wrote on y's wall". The wall is hidden on the profile I'm talking about.

The photo album settings are obviously on "Friends only" and always were, so that's not my question. What changed?

Change your privacy settings under "posts by me" to Friends of Friends, but keep everything else to friends only.
