There are many photo-gallery programs available. Zoph is different, as it concentrates on the management of large collection of photos instead of just showing them on the Web. It can store a lot of information about your photos, including the regular EXIF info, photographer, location, title, description, rating, and the people in the photo. Photos can appear in multiple albums and categories. Additional features include search, slideshows, lightboxes, email, access privileges, and multiple languages.
Photo Organizer is a Web-based multi-user photo management tool that was designed for professional photographers. It offers a searchable photo database that supports photo version control, a datebook with client management, photo submission history, EXIF, IPTC, XML, and XMP, user quotas, and printing labels and color brochures. It uses ImageMagick and DCRAW to handle over a hundred image formats, and relies on PostgreSQL as its database backend.
Ansel is a Horde photo gallery that provides functionality for managing unlimited photo galleries, with thumbnails, paging, EXIF data, and permissions on a per-gallery basis. It also provides a number of features not normally found in Web-based photo galleries, including cropping, resizing, rotating, watermarking, and greyscale effects.
