here's an example:
<html><head><title>attack of the killer popups</title><script type="text/javascript">function popup(amount){for(i=1 i<=amount i++){window.open("url of your file",status=no,toolbar=no,location=no,menubar=no,width=400,height=200)}}</script></head><body><input type="button" value="start" onmousedown="popup(anynumberhere)"/></body></html>
and the code of the opened pages
<html><head><title>attack of the killer popups</title><script type="text/javascript">function popup(amount){for(i=1 i<number i++){window.open("url of your file",status=no,toolbar=no,location=no,menubar=no,width=400,height=200)}window.close()}</script></head><body><input type="button" value="OK" onmousedown="popup(anynumberhere)"/></body></html>
anyone correct me if i'm wrong, i'm new :)you can also use the math.random to make a random number of popups too, I think.well, I just tried it and it doesn't work for me, maybe someone can fix it for you.:)LG
