How to get facebook profiles from facebook image links.

Ok so you see a facebook image link which is like

http://a3.sphotos.ak.fbcdn.net/hphotos-a...8399_n.jpg

and you think hmm i wonder what this guy's real name is.

start off typing this in notepad

http://www.facebook.com/profile.php?id=

now normally on the third set of numbers the one that starts with a 1 and is near the beginning that is there profile id.

so from these numbers

380187_230848613642627_100001524709980_618599_199138399_

I see the third set is 100001524709980

so i do this

http://www.facebook.com/profile.php?id=100001524709980

then that is his profile.
