Create a gallery with your pictures and videos hosted on Flickr. Doesn't use any backend so you can host this gallery wherever you want.
Just download the project, or git clone it, and place the content of the /public directory in the public area of your web server.
Then create a config.js file, based on example.config.js, and simply put your username and Flickr API key. You can get an API key for free here http://www.flickr.com/services/api/misc.api_keys.html
Enjoy!
