So I have a jquery countdown, and a box (for the image/s).

I would like a new image (from a folder) to appear in the box each time the countdown reaches 0.

Here is a snippet of my countdown clock:

Code:
$('#counter_2').countdown({
          image: 'img/digits.png',
          startTime: '60:00',
          timerEnd: function(){ alert('end!'); },
          format: 'hh:ss'
        });

So what would I need to do this, please and thanks!

(Didn't know what part of the forum this would go in, so put it here).
