Pyxy-gallery is an AJAX image gallery in PHP and JavaScript, which optionally uses lightbox.js. It is designed to be an ultra-light-weight, "drop-in" image gallery. <y uses lightbox.js. It is designed to be an ultra-light-weight, "drop-in" image gallery.
Its features include:
AJAX shininess
Users can browse your pictures without leaving a page. This provides for a smoother, more continuous user experience. Pyxy also uses fragment identifiers to let you bookmark and link to individual pages within the gallery.
HTTP support
You’d think this was trivial, but it’s not: Unlike some drop-in 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 drastically reduce loading time latencies.
Ultra-lightweight
Just drop it in and go! Configuration is optional. Pyxy requires PHP version 4.3.0 or later, with the GD image library.
