This is way beyond my skill level, but there is only one way to get there right?

Here's what I am trying to do:
I want to populate a scrolling content box with thumbnails from a directory on my website. That's step 1.

Step 2, if I can ever figure out how to get here, is when a user would click a thumbnail in content box 1, the full size image would load in the larger content box 2, with a transition. This would also not be hard coded and would pull a corresponding named image from a directory on my website.

Coding wise, I can do it in other languages but flash is very new to me, thus why I started here with koolmoves. I know the logic involved but I just can't seem to get it all together with Koolmoves.

Can anyone help me out? I have read a few of the tutorials available and tried to tear them apart, it's just not what I am trying to do.
