Making the infinite scroller advance via clicking, instead of mouse movement

Hello all,

I have a question…Of course…I want to make Kirupa’s infinite scroller advance by clicking an arrow instead of on mouse movement. Does anyone know if this is possible? The tutorial is here…

Essentially I want a line of images to be advanced by the clicking of a button (arrow). BUT I want the images to be back to back so you can see a couple at a time.

THANKS!
