Who painted the first known picture of Jesus?

The earliest known pictures of Jesus are anonymous works dating to the 3rd century A.D. Due to the age and informal nature of the pictures, it is impossible to name the artists who created them.

One of the earliest pictures of Jesus was painted on the wall of the St. Callisto catacomb in Rome around the beginning of the 3rd century. It depicts a bearded Jesus working as a shepherd. Another image that may have been drawn as early as the 1st century A.D. is the Alexamenos graffito, a piece of Roman wall graffiti that depicts a crucified man and a worshipper. It was likely drawn to mock a Christian named Alexamenos.
