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.
Picasa is Google's photo organizer. It makes it easy to find, edit, and share digital photos. It automatically locates and remembers all pictures and sorts them into visual albums organized by date with recognizable folder names. You can drag and drop to arrange albums and make labels to create new groups. This Linux version mostly has the same features as the Windows version, and is based on a modified version of Wine.
GPicView is a simple and fast image viewer with low memory usage. It's aimed at replacing the default image viewer of current desktop systems. Fast startup, low memory usage, and a simple user interface make it a good choice for a default viewer. It is extremely lightweight and fast with low memory usage, has a simple and intuitive interface, minimal library dependencies (only GTK+ is used), and doesn't require any specific desktop environment. It was inspired by the Windows XP image viewer and gimmage.
F-Spot is a personal photo management application for the GNOME desktop. It simplifies digital photography by providing intuitive tools to help you share, touch-up, find, and organize your images. These tools include editing, color adjustments, tags, Photo CD creation, and exporting for upload.
Vis/Space is a client-server system for visually exploring data structures in 3D virtual space. It allows the placement of various data sources in a three-dimensional environment. Custom search terms can be entered into a query field, or can be navigated to and from an existing object. All objects like images and "text screens" can be moved around. A single click on an image shows the full-resolution version in the foreground. Whole collections of images can be moved. A click to the cube also toggles among several different possible layouts. Data sources include search engines, microblogging, Wikipedia, image/video search, and 4chan.
