Remove comment & blog sidebar on photos

Hi Sakin, Sorry for posting in the wrong place before. I'm almost done with my website design... it's been great fun! Using Tiled Galleries in Jetpack, click on an image in the gallery. Page comes up with photo and comment window at the bottom. Some of the galleries also show the blog sidebar. How can I remove both? Look at www.golfmetaberoutin.com/wp Select English if needed Galleries...Haste...click on one photo -> comment dialog Galleries...Facolli...click on one photo -> comment dialog & blog sidebar Thanks in advance.
