Facebook question: How do I keep my pic off a friend's list?

Actually not me, personally. Heck, I’m flattered when anyone notices me, but anyway. . .

I have a *couple of friends who have several mutual friends in common, and their pic does not show up in the “mutual friends” list. How do they keep it from showing?

*Probably more, but I’ve just noticed it on a few.


I am friends with Bob and Carol and Ted and Alice.

We have mutual friends of Bert, Ernie and a number of others.

Bert and Ernie do not show up in as ‘mutual friends’ when I look at Bob’s, Carol’s, Ted’s, or Alice’s friends list. How dey do dat?
