Who know the name of script or pluging for clicking thumb and picture pops in the middle?
 

You know when you click on thumbnail and picture comes up in the middle of screen, sort of like smooth flash format? NALEM has something like that on his site.

Are you talking about Lightbox, Fancybox, etc?
