I use a randomizer found at:
http://tech.irt.org/articles/js033/
Put this in the <head> section of your html page:
<script language="JavaScript"><!--
// The Central Randomizer 1.3 (C) 1997 by Paul Houle (houle@msc.cornell.edu)
// See:
http://www.msc.cornell.edu/~houle/ja...andomizer.html
rnd.today=new Date();
rnd.seed=rnd.today.getTime();
function rnd() {
rnd.seed = (rnd.seed*9301+49297) % 233280;
return rnd.seed/(233280.0);
};
function rand(number) {
return Math.ceil(rnd()*number);
};
// end central randomizer. -->
</script>
Then, where you want the quicktime movie to appear, put:
<script language="javascript"><!--
document.write('<embed src="movie' + rand(#) + '.mov" width="240" height="196" align="left"></embed>');
//--></script>
Replace the # with the actual number of movies you have. This assumes they are named "movie1.mov, movie2.mov, etc."
Hope this helps.
