Scotty's Infinite Scroller Customizing

I am trying to customize Scotty’s infinite scroller re-sizable gallery, which i got from http://kirupa.com/forum/showthread.php?t=87388.

  • change the infinite menu scroll the images to the left when mouse is to the right, and vise versa. (Seems more logical that way)

  • add caption

  • add margin to the thumbnails so that aren’t but up right against eachother.

Any help to steer me in the right direction?

Thanks!
