I took this picture in March on the way back from Pattaya. I forgot to get my wife to write down the name of the temple but it's located along the main highway from Saraburi to Korat (it's located in the flat area once you pass through the mountains and large lake). Looking at GoogleEarth I believe it's near a village called Sung Noen. This temple is very large and if you happen to pass between Korat and Saraburi you can't miss this.
