KPhotoAlbum
KPhotoAlbum is an image viewer and organizer for Unix-like systems created and maintained by Jesper K. Pedersen. The core philosophy behind its creation was that it should be easy for users to annotate images and videos taken with a digital camera. Users can search for images based on those annotations and use the results in a variety of ways. Features include slideshows, annotation, KIPI plugin support for manipulating images, and Boolean searches.
