Pyxy-gallery is a single file drop-in PHP script which uses AJAX to let you browse your pictures without leaving the page - saving time and bandwidth, and reducing server load. AJAX skeptics can be reassured: Pyxy uses fragment identifiers to let you bookmark and link to individual pages within the gallery. Unlike some simple gallery scripts, Pyxy uses the HTTP headers that browsers send to determine whether or not to re-send image thumbnails.It supports keep-alive connections to reduce loading times.
