After some trial and error I figured it out. You'll need to copy and paste the script for as many images you want the mouseover effect for. In each script you'll also need to define the target image space as something unique from the others. For example, for the first image you use "targetIMG". For the second image differentiate it from the first by calling it something like "targetIMG2". You can call it whatever you want. If you don't do this you'll only change the rollover image for the first defined mouseover space. Hope this helps!
