FlickrEdit is a free application for Windows that allows us to manage our Flickr Account and profile as well as perform some additional tasks with our photos.
We can add or eliminate pictures, backup our images from our PC to Flickr or viceversa. It allows you to edit some photos online too.
FlickrEdit also includes an album manager, a search box and a contact manager. If you are a Flickr user, it can be really useful.
