The Tibetan Wheel of Life is perhaps the most common of all pictures in Buddhist art and is seen on the walls of monasteries and painted scrolls all over Tibet, Nepal and other Himalayan countries. The 23 parts of the painting represent in visual terms some of the more fundamental teachings in Buddhism such as the 12 steps of dependent origination, the karmic laws of cause and effect, and the three kleshas of ignorance, greed and hatred. exoticindiaart.com, and ccbs.ntu.edu.tw are good websites.
