I think its good to focus upon the person of Jesus Christ, not so much an image because they can be vain at times and not promote what is sound, especially the pictures of Jesus as a white hippy dude, with long hair and soft hands... that's not Jesus, that's a white dude with long hair. (the catholic Jesus).
Those who like these images, are usually into some form of idolatry, because that's why they have them, its a projection of there idol, they want this Jesus, a nice kind person, too bad Jesus ain't just kind and meek, but also strong, fearsome and offensive at the same time, a consuming fire, a righteous person who hates wickedness (Hebrews 1:8-9).
Jesus had dark skin, probably looked ordinary and uglyish:
Isaiah 53:2 He had no beauty or majesty to attract us to him,
nothing in his appearance that we should desire him.
I think about that statement there from Isaiah, Jesus would have looked very ordinary and uglyish to most people, thats a pretty strong verse about Jesus in his humanity, you can't get around it, its the word of God.
