Flickr Gallery 0.4: Plugin for WordPress. This one should be really cool. From what I can tell from the plugin, you post to Flickr and the plugin will get the photographs from Flickr, cache them locally and then post them on your blog. REST is used to make the API calls to Flickr to get the information. The coolest part of this plugin is that it incorporates the “Notes” of Flickr. This code can be used outside of WordPress as well since it really does not use any of the WordPress code.
