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.
jBrout is a photo manager. It can manage albums and photos, tag photos with IPTC keywords, use internal JPEG thumbnails, add comments to photos and albums, losslessly rotate JPEG files and internal JPEG thumbnails, and use EXIF info. It uses plugins to add a variety of features such as exporting to HTML, acting like an HTTP server, and exporting to email. It works without a database, and has been tested with a collection of over 20,000 photos.
