Help with camera panning tutorial

I have done the tutorial called "Merry-go-round of Spinning Images found at
it was a good tutorial. However, does anyone know how to use different images instead of just the one movie clip/button/graphic. i would like to use this effect but to have different pictures in each square for example.
If anyone can help I would be grateful.
I know that it is in the scripting, but can anyone tell me where the changes in the script need to be made in order to achieve this?
Thanks in advance.
