I say an article about a week back about Rembrandt's painting(s) of Jesus on Veith's blog (The Face of Jesus).
What's interesting to me is two things, and they both are related. One, how different people in different ages and countries have depicted Jesus in art. I think it's healthy and good to have Jesus looking different, aka, not ALWAYS a 1st century Galiliean (though those are probably my favorite ones...). This personalizes him and can move people to engage the good news with their senses. Of course, the good news itself that Jesus is Lord and God raised him from the dead is God's power (Romans 1), but that power works psychologically and through our senses.
