Are Christian depictions of Jesus and Mary considered accurate?

Jesus and Mary in Christianity is Prophet Isa and his mother Maryam in Islam; see Jesus in Islam . It seems Christianity doesn't have the same restrictions as Islam regarding depictions of Jesus, and they're everywhere, particularly around Christmas. Muslims avoid looking at images of Prophet Muhammad, but appear less adverse to images of Prophet Isa. There's this question https://islam.stackexchange.com/q/12077/17163 , which is currently unanswered. However, I'm interested in a different question which might also play a role: **Question**: Are Christian depictions of Jesus and Mary considered accurate?
