Antony is an off-line and cross platform tool for organizing and sharing photos that makes it possible for a group of peers to keep a common photo, image, or picture collection current and synchronized. Users can tag images (year, event name, event place, or event type, photographer, people, comments). Images are stored in a local file system, and tags are stored in an SQLite database. To identify images, their MD5 sum is used, which makes it possible for users to merge collections. Images can be searched using tags, and images and metadata can be exported to a folder. A thumbnail representation and a zooming image viewer are provided.
