Urgent Facebook privacy question. Please help me with damage control :( :(

Asked by marmoset (1311) September 10th, 2011 from iPhone

A fb friend of mine posted pics of me, tagged with my name, that I absolutely don’t want some of my friends to see. I happened to check my email and notice this, and I got him to take them down within ten minutes. What does this mean? Do ONLY those friends of mine who happened to look at fb during those 10 mins see the pics? What about people reading fb feeds? Were the images sent to them? Who saw or will see these photos?? Also urgent: will it help at all (in terms of preventing people from seeing them) if I unfriend this person?
