FlickrSync monitors any image folders of your choosing and syncs their contents to your Flickr account. It s great, FlickrSync brings a new level of functionality to keeping desktop folders in sync with your Flickr account you only have to choose the folder or folders you want to sync and in case you include a new picture in that folder it will be automatically uploaded to your Flickr account. Amazing!
At first it is not extremely easy but you will get used to it in a few minutes. In fact you can manage your photos locally and the results will be really good.
