Begin at random place on timeline

OK, I’ve searched all day for an answer for this to no avail. I’m counting on you:

I have a very simple Flash file made up of 10 frames, each with a different picture or movie clip in it. All I want to happen is for the movie to begin at a different (random) point each time the page is loaded.

What is the best (and easiest) way to accomplish this??? Please help.

Muchas Gracias!
