Please help! Script on MAC IE

I have this script from actionscript.org. Its a script that loads jpg dyn. into a MC that resizes. The only problem is it does not work on MAC IE or netscape. The images loaded randomly in the movie. I really want to use this script for my site. I’ve posted this problem on other forums and have seen it posted as well. But nobody has a solution. So if you can take a look at script and see if this problem can be solved. Please Help. Thanks ron
