: Prior to DHTML, viewing the images behind the thumbnails meant displaying them in their own browser window (by setting a URL to the image's path), which interrupts your visitor's browsing experience. This cool DHTML script allows you to show images inline on the page, with the images downloaded only when called. The displayed image is dragable, so the user can adjust its position dynamically. Browsers other than IE 4+ and NS 6+ will automatically resort to the old method of displaying the images- in their own browser window. What else could you ask for in a thumbnail viewer?
