Side Scrolling Chapter Menu

I'm trying to create a side scrolling chapter menu and was wondering if anyone knows some script that would get me started.

Basically I want to scroll through chapter images using left and right arrow buttons, so the menu would start like this:

< #1 #2 #3 >

Then by clicking on the right arrow button it would then look like this:

< #4 #5 #6 >

And so on. The version I have built simply replaces the images (#1 replaced with #4, #2 replaced with #5 and so on). But I would love to make them scroll so the new images come in as if they are all on the track moving left and right.

Any ideas on how to do this or other help would be greatly appreciated.
