To navigate the gallery you can either click on a thumbnail picture or you can put your curser on the sides of the larger image to bring up an arrow. You can then click on the arrow to go to the next picture. You can also start a slideshow of all the pictures in the gallery by moving your curser to the center of the large image to bring up a circle with a triangle in it. Click it and this will start your slideshow. To stop the slideshow, click the center button again. Enjoy!!
