Loading dynamic thumbnails

I have a question about the tutorial on:
http://www.kirupa.com/developer/mx2004/thumbnails.htm

Instead of loading the thumbnails in a scroller sideways, how can I load the thumbnails in a column like this:

thumb1 thumb2
thumb3 thumb4

target_mc._x =(k%2)*(target_mc._width+10);
target_mc._y =Math.floor(k/2)*(target_mc._height+10);

Thanks Scotty…

Scotty,
At this point Im trying to load 6 thumbnails at a time and the rest I want to load when I click on the next button. How can I do this?

Maybe this will help
