This has a few photos of statues of the Buddha and a couple of temples. I find the photo that looks corrupted the most interesting, as I think there is data hidden in there (similar to 4chan.js if you've ever heard of that).
The file names of the photos are shrine.jpg, statue.jpg, spire.jpg, pillar.jpg, and cave.jpg.
