The ceiling paintings (via) in the Ajanta Caves are amazing, but good photos of them are hard to find -
The caves, east of Mumbai, were chiselled out of the rock, starting as early as the 2nd century BC; they were abandoned by about 500AD, and rediscovered by English officers during a tiger hunt in 1819.

And the wall sculptures are amazing. A good selection is here.
This one caught my eye -
