We have examined several applications for working with Flickr before, and they all have one thing in common: they focus on uploading images from the desktop. But uploading only scratches the surface of what the Web service can do. Desktop Flickr Organizer (DFO) gives you a lot more power.
There is nothing wrong with Flickr uploaders, but if you are a heavy Flickr user, you need to do more than just upload pictures. You need to manage your existing photos and sets, create new sets, edit tags, descriptions, and permissions, contribute to group pools, and so on. Using DFO, you can do all that, performing most (but not all) of the tasks in Flickr's online management tool Organizr.
