LinPHA is an easy-to-use, multilingual, flexible photo/image archive/album/gallery written in PHP. It uses an SQL database (MySQL/PostgreSQL/SQLite) to store information about your pictures. It comes with an HTML-based installer, so you don't need experience in setting up SQL databases. Thumbnails are created as needed and stored in the SQL DB. It features complete user management, top ten statistics, hidden albums, different themes, slideshow, filemanager, uploader, watermarks, benchmark, printing, and more.
Eyes Of Lynx is a Web-based application that allows you to share, examine, and manage your photo albums. It's designed to be fast, intuitive, and very powerful. Its key features include an original and innovative interface, zoom and rotation tools, auto-rotation of photos when an orientation is provided in EXIF data (information stored by digital cameras), a cache of images in a smaller/intermediate size to increase display and loading speeds, thumbnail image navigation, and more.
AgileGallery is a photo gallery that processes the XML output from Picasa, generates paging and thumbnails, and displays the full sized photos along with any captions entered in Picasa. AgileGallery presently comes in two flavors: one that uses AJAX for the interface and one that uses Flash. AgileGallery does not require any server-side technology to generate photo galleries.
