NextGen image issue

I am unable to figure out how to get images to show up on same page enclosed in frame, when clicked on. Sample page of issue. http://www.endlesspursuits.com/olefogey-blog/homefront/aris-liftoff

I want the image to appear as it does on the thumbnail, in a frame or at the very least a more formal image.
Suggestions?
