Quick and dirty script to download an Imgur image album to a directory.
GIFs over 2 MB are downloaded as WebM. That probably seems like a weird decision.
Register an Imgur application of type "Anonymous usage" and copy the Client ID. Then:
$ npm install -g imgur-album-download
$ imgur2rss <client-id> <album-id> <output-dir>
