J-Flickr provides shortcode (e.g. [flickr key="value"]) syntax access to the Flickr API.
J-Flickr is designed to be as unintrusive as possible in giving you access to the Flickr API service. This means that you are not limited to the methods you can call or hamstrung by the output of the plugin. If you want to search for photos with an Attribution License uploaded last year then you can, just as you can get a list of your public contacts or talk to the Flickr Pandas. Essentially you construct the shortcode as if making an API call and then either use one of the existing general templates or make your own! The templates are in XSL and operate directly on the XML sent back from Flickr so you're never wanting for data that other plugins may not expose.
