  // *Before May 25th 2010 large photos only exist for very large original images.
  // **Original photos behave a little differently. They have their own secret (called originalsecret in responses) and a variable file extension (called originalformat in responses). These values are returned via the API only when the caller has permission to view the original size (based on a user preference and various other criteria). The values are returned by the flickr.photos.getInfo method and by any method that returns a list of photos and allows an extras parameter (with a value of original_format), such as flickr.photos.search. The flickr.photos.getSizes method, as always, will return the full original URL where permissions allow.
