There are many other temples in Bangkok outside of Wat Phra Kaew & Grand Palace grounds, but within walking distance for the fit. In this one are good examples of currently-worshipped images of Buddha.

Notice the gold-leaf pressed to the images to show worship and gain merit. Many revered Buddha images have so much gold leaf applied to them by their devout worshippers that their detail is totally obscured.

This is, I think, in Wat Pho which houses the largest "reclining" Buddha and that is a Must See. It is too big to photograph well...
