Exorcist Guy here.
Jesus has no palm-holes. He only has wrist-holes. It is impossible to crucify someone by driving nails through their palms, as the weight of their body when the cross is turned upright would tear it straight through their hand and they'd fall off. Thusly, crucifixion was done through the wrists, and you know any painting showing it through the palms was painted by a person who wasn't present at that or any other crucifixion and only knows about the process second-hand.
Who says Christians don't like SCIENCE?
