Resize Border_V3

Hey guys i need some help understanding this tutorial and source code. I am playing around with the source file for Resize Border_V3 (http://www.kirupa.com/forum/showthread.php?t=87388) my question is… is there a way of having thumbnails on the bottom like the kirupa add ing thumbnail tutorial provides ([URL=“http://www.kirupa.com/developer/mx2004/thumbnails.htm”]http://www.kirupa.com/developer/mx2004/thumbnails.htm) while the borders get resized. I tried but i am very new at this and i can’t seem to even be close to it. All the help i could get would be really grateful.

Thanks
Ocenus.
