Chaotic Horde

Ive been experimenting all night trying to find a way to replace text/numbers with an actual image of that number. If I had the number 213, how would I replace it with the image "2.gif" as well as the images "1.gif" and "3.gif". The only tutorial I could find that does this is the http://www.kirupa.com/developer/mx/countdown.htm . Unfortunately, the code was a bit overly complex for me and what I need. Is there a way to break down 213 into 3 seperate numbers ( "2" "1" "3" )? I think I would be fine If I could manage that.

I was hoping some one here could show me a simplified way of doing this or at least point me in the right direction. Thanks.
