Newbie thumbnail tutorial troubles

Could someone suggest a way in which to create a vertical scroller for the “adding Thumbnails” tutorial?

If this is too monumental, or esoteric a question, could someone either point the way or suggest a method in which I could have the thumbnails load into a static empty MC area that would be vertically oriented?

Is this feasible? or is my question too broad.

Please be gentle, you knew I was a newbie from the title…
