/**
 * Strictly Jquery based flickr thickboxing.
 * Will find and destroy (thickbox) any images meeting the following
 * conditions:
 *
 * - Includes "flickr.com" in its src attribute.
 * - Is not contained within a link.
 * - Flickr API request succeeds.
 *
 * @TODO: probably should cache API call results so that it doesn't
 * hit flickr every time the user clicks the thickbox.
 *
 * @TODO: probably should have the API key stored & retrieved via
 * Drupal.settings... but who's gonna release this anyway? : )
