i've been researching a lot of sites lately as inspiration for my own, and come across this script so very many times. it's the one that overlays images on top of the screen within the browser, so you don't have to open another window. it's simple and clean, and certainly worth considering. in my lunch (quarter) hour today i found the actual script: Lightbox 2.
Now, if only i knew what all that technical jargon meant. hm. must get on that.
