Its like rsync for Flickr!
A python script to manage synchronising a local directory of photos with Flickr based on an rsync interaction pattern.
Synchronise a local folder of media files to flickr or from flickr to a local folder, supports filters for including or excluding folders and files based on a regular expression pattern. No surprises flickr-rsync will never delete or modify files in the destination, it will only add new files or skip existing ones.
List photos from the local file system or from flickr in diff-friendly formats.
flickr-rsync is distributed under the very permissive MIT License, use and modify it for personal or commercial use.
