facebook

So I was looking at the facebook HTML with firebug, and I chanced upon this image and came to the conclusion that facebook uses this large image (with tricky image positioning code) rather than many small ones for its graphical elements. Is this more efficient than storing many small images?

Can anybody give any clues as to why facebook would do this.
