where is my account picture?

When I first opened my Macbook Pro, it had me take a picture to use for my account. Where does it store this picture?

Check Finder/Your Account (under Places)/Pictures/Photo Booth. Your pictures taken with your Mac cam should be in that folder...

I looked everywhere. I can't find it.

Your pic is either where Noels said it was which is where all Photobooth pictures are stored or the Library off the first folder you open when you click on the Hard Drive and in the Desktop Pictures folder inside of that Library. Reason I am suggesting there is after all it was taken as a Desktop picture!

This is the Library I am talking about. See pic below.

It wasn't taken as a desktop picture, it was taken as a user picture. I even tried looking in the "User Pictures" folder in the "Library" folder, and it's not there. Is my picture only imprinted into my account and is not saved anywhere?
