DigicaMerge is a commandline tool to merge directories of pictures taken with digital cameras. If you've got a digital camera, your hard disk probably contains many directories full of pictures all named with the same names. This utility allows you to merge such directories' contents into a new directory, and renames all the pictures on the fly, ensuring no filename clash will occur. You can define your own naming scheme, using either a set of predefined variables or any recognized Exif tag which may be present in your pictures, and also specify a pattern to select only certain files.
exiftags parses a JPEG file looking for Exif (Exchangeable Image File) data, formatting, and printing image properties. Digital cameras typically add Exif data to the image files they produce containing information about the camera and digitized image. exiftags includes support for some camera manufacturer-specific properties.
digiKam is an advanced digital photo management application that makes importing and organizing digital photos a trivial task. Photos can be organized in albums, which can be sorted chronologically, by directory layout, or by custom collections, and they can be tagged, commented, and rated. digiKam makes use of a fast and robust database to store meta-information, which makes adding and editing comments and tags very reliable. Metadata can also be stored inside pictures using Exif and IPTC. An embedded image editor and a standalone application named showfoto have simple but powerful features for editing your pictures with filters and correction tools.
iOta (Image Organization Tool and Archiver) is a tool to manage, organize, index, archive, and Web-publish your digital photography collection. It is backed by a BerkeleyDB database. The KDE/QT based front-end is designed to be simple, yet powerful. iOta allows the user to generate, uniquely rename, and index images to an embedded database. The user can also caption and describe each image, generate thumbnails and browsable HTML indexes, archive directories of images onto CDR, and search and edit properties of each photograph in the user's collection. In addition, all this information also travels with the image itself in the thumbnail EXIF header.
