To View these images in stereo you must cross your eyes. Don't worry, it's a natural thing your eyes do all day as you look at anything close up. When your eyes are crossed you should see three images. The one in the center should be the right and left images merged. They should be in stereo or 3-d. The effect is dramatic when it happens, but you may need  to work a little to get it. Sometimes you may need to rotate your head a little to align the images.
