Thumbnails not showing at correct size

In options, I have the thumbnails set to be at 200 x 144. After uploading the images to the gallery, and viewing it looked for a second that it was going to show it at these dimensions, but instead shows it at these tiny thumbnails. How do I fix this? See http://74.53.94.225/~pwenergy/gallery/ to see what I mean.
