Do you pray to Leonardo Da Vinci?

Saw that picture of 'Thank God I'm an atheist' which is the same one, supposedly of a white Jesus, my mother used to get me to pray to as a child. Did you know that Leonardo Da Vinci was a talented artist and also scientist who was an atheist also? He thought it would be a great laugh if he created an image of himself and copied it using chemicals we now use in photocopying, onto a cloth, then said it was an image of Jesus on a shroud. Then everyone would pray to his face as though he were Jesus! When you think about it, what colour would Jesus' skin have been, coming from Israel anyway - not quite as pale as that Jesus painting maybe? Also should we pray to Jesus anyway or just to his father - Matthew 6:9 and psalm 83:18?
