Random loading images

programming flash
1

I have done a random loading file using this tutorial:
http://www.kirupa.com/developer/mx/loadingrandombackground.htm
And really like to know if there is a way to put 2 different simultaneous
random loading images in a single flash file using this code:

choice = Math.round(Math.random()*5);
switch (choice) {
case 0 :
location.loadMovie("image0.swf");
break;
case 1 :
location.loadMovie("image1.swf");
break;
case 2 :
location.loadMovie("image2.swf");
break;
case 3 :
location.loadMovie("image3.swf");
break;
case 4 :
location.loadMovie("image4.swf");
break;
case 5 :
location.loadMovie("image5.swf");
break;
}

Tried many times without luck, need some help!
