Online photo sharing site Flickr offers a tool for uploading images and videos. But the Flickr Uploadr doesn't let you keep your photos synchronized with desktop folders the way that the third party FlickrSync does.

You can configure FlickrSync to watch specific folders on your Windows desktop and sync them up with your Flickr account. In other words, whenever you add files to the desktop folders and hit the sync button, they'll be sent to Flickr. If you delete the images from your local folders, they can be removed from Flickr when you hit the sync button again (although you can configure the application never to delete photos from Flickr).

FlickrSync offers only one-way synchronization. While changes made on your desktop will be reflected online, making the program an excellent tool for managing your Flickr photosets, FlickrSync will never delete photos stored on your desktop. While two-way synchronization might be a nice feature to have, my guess is the developer didn't want to have to deal with angry users complaining that the program deleted their only copies of prized photos.
