A Python script to grab all your photos from flickr and dump them into a directory, organized into folders by set name. The filenames are named based on the combo of the photo's original date-taken and the Flickr photo ID. Save the "Large"/"Medium" sized images from Flickr for usage with syncing these images to your iPhone via iTunes, since iTunes ends-up resizing these images during sync anyways.

Original author is "Colm MacCárthaigh" ("Flickrtouchr.py - Keep your Flickr album and favourites on an iPod Touch or iPhone" blog post).

Modified by "Dan Benjamin" ("Backing up Flickr" blog post, GitHub repo) to download full-size original images and improvements in handling UTF8 file and photoset names.

Further tweaked by me to minimize the amount of Flickr API calls made and to name files based on their date-taken meta-data so that the files sort chronologically.

Run it like this:

mkdir FlickrBackupFolder
python flickrtouchr.py FlickrBackupFolder

You'll be prompted to authorize with Flickr, and then the magic happens.
