You may have to do some hunting first, but if you click on the CruiseReviews.com link (first one in th elist above) it will take you back to the home page. Click on RCL under the Cruise reviews at the top. Then from there you can choose the Mariner and see a bunch of reviews of it. I'm sure someone in that list has included a link to pictures.
