cool image viewer

hey there, this should (hopefully) be a nice quick easy project! im making a web site to sell personal prints of my photos. and in the gallery we see the thumbnails of my pics next to each other. what i want is an image viewer - when the user clicks an image, a much bigger version of the image appears, with the title below it, the price, and a buy it now button which goes to paypal, where you can pay for it. perhaps i will add another line of text later (eg the size) so please let this be easily editable. plus ill be adding more images so also let the code be simple enough for me to add more pics to do the same thing when clicked. (ive got dreamweaver so if you explain how to do it in easy steps, thats fine) as its an art site, i want a pretty cool image viewer, lol please dont use one of the freely downloadable ones you can find on the internet - ive seen them all! sorry im unable to define "cool", but please let me know your ideas! thanks! torre
