I'm not sure why any one would give this a thumbs down, other than some people are idiots. It's a rather nicely done photo gallery and makes excellent use of ajax to advance through the photos and update the comments and description along with the photos. This example is very close to what I'd like to see in D7 as far as browsing through a photo album is concerned.
