Queen Mary 2
For comparison, here are links to the various "Our Ships" pages on the Cunard web site where each of the bridge webcam images can be found via a bridge webcam link. These pages also provide additional information including the ship's location and the current time at that location.
In my experience, the source for the webcam images displayed on this page updates much more frequently than the source for the webcam images on the Cunard web site.
