A Python script to grab all your photos from flickr and dump them into a directory, organized into folders by set name. Original author is "Colm MacCárthaigh":http://www.stdlib.net/~colmmacc/. Changes include tweaks to download full-size original images and improvements in handling UTF8 file and photoset names. Run it like this:
mkdir FlickrBackupFolder
python flickrtouchr.py FlickrBackupFolder
You'll be prompted to authorize with Flickr, and then the magic happens.
