FlickrSync

Not sure whether this is right for me or not. It’s called FlickrSync.

FlickrSync is a freeware synchronization application for users. It displays your local folders and your flickr sets and it can establish synchronization rules between them. This way you can manage all your locally and FlickrSync will keep them updated in flickr.

Available for XP SP2 and .Net 3.0 only.
