Scroll images

Trying to figure out how to add more images to this image scroller i found on this forum. Cant seem to find the forum threads now. But anyway, if anyone has seen this example(attached a screenshot) and can help. I would appreciate it. I can add more images(there were three in the original fla), but when i add more they show up out out of sequence or duplicated. I know i need to adjust the math in the actionscript and i have tried everything but nothing seems to work. I want to add at least 25 images.

I just relized i can upload a zip… heh heh. So here is the fla for anyone to play with.
