Shotwell is a new open source photo organizer application designed for the GNOME desktop environment. It allows you to import photos from your camera, view and edit them, and share them with others.
Here are some key features of "Shotwell":
· import photos from any digital camera supported by gPhoto
· automatically organize events containing photos taken at the same time
· rotate, mirror, and crop photos
· export photos as they are or by specifying dimensions and JPEG quality to reduce size
