Exiv2 is a C++ library and a command line utility for managing image metadata. It provides fast and easy read and write access to the Exif, IPTC, and XMP metadata of images in many formats. The Exiv2 command line utility prints Exif, IPTC, and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image.
Fotoon is an application that helps users manage and organize photos in an easy and fast way. It allows the creation of albums and sub-albums containing photos that can be labeled with tags in a drag-and-drop manner. Tags can be user-defined, if none can be found in the template collection. Photos can easily be selected according to several criteria (tags, legends, descriptions, etc.). Albums are saved in an XML format.
JCap is a Java application for adding captions and descriptions to your digital photograph collection and includes a search dialog for finding photos later. It is completely self-contained; it doesn't require a separate database application or Web server to run. Captions, descriptions, and keywords are stored in plain text files in the same folder as the images they describe and can be read by any application that can read text files. The primary goals are: to help you find photos later, to help share photos with others, and to be able to read photo captions and descriptions thirty years from now on whatever computer you happen to have at the time.
My Photo Gallery is a Web-based photo gallery that also supports non-image filetypes. It is easy to setup and even easier to maintain. Slick-looking image galleries and thumbnails are generated on the fly from any root directory that you specify. Albums can be created using the included Web-based adiminstration tool or by creating a directory and copying your pictures and files to that directory. A Web administration interface is available to help add descriptions, rename images, rotate images (losslessly), and more. It includes advanced features such as image logging, renaming, resizing, image rotation, smilies, and visitor comments. Unlimited filetypes may be recognized, and custom images for them can be displayed in your galleries, allowing you to archive MP3s, MPEGs, AVIs, etc.
OrbySPV (Sequential Panoramic Viewer) gives you the ability to create highly interactive virtual tours, similiar to the Google Maps Street View, using your own panaromic images. The Orby experience is not like the other virtual tours that you may have seen around the Web, where you stand in one spot and look around in a static 360 degree bubble. Orby has that ability, but instead of standing in a single position, you can actually walk around in the captured environment, stop at any position, and zoom and rotate as much as you want.
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.
Qtpfsgui is an open source graphical user interface application that aims to provide a workflow for HDR imaging.
