Mulitple thumbs w.click action

Hi all, I hope I am not repeating this. What I want to do is:

Dynamicaly load images as thumbs on to the stage and make them clickable so that they may activate or load something else.

I have searched the forum and found many multiple image loading techniques (from XML etc), but how do I make the thumbs into buttons and load other swf’s (e.g. as portfolio items)?

Similar to something I saw here: http://www.gridplane.com/v3/ - which uses a grid layout to load each thumb, when clicked it opens up the item.

Any ideas or directions would be very welcomed!!!
Thanks in advance.
