Ya to some extent, photos or paintings of Jesus can be misleading. Consider all the different variations of his physical form that have been depicted over the years and how different they are. Especially the Catholic religion seems to portray him as very "meek and mild" while perhaps more modern forms of Christianity portray him as they think he might be today - sociable and engaging.
In Paramahansa Yogananda's book, The Second Coming of Christ, he describes Jesus' likeness to that painted by noted artist Heinrich Hofmann, as the saint had a visitation by Jesus and could see the most similarity in physical likeness with this artist. Perhaps also it's not about focus on what Christ looked like but more so the energy he embodied. I wonder what it would feel like to be "with" him.
12 And the Lord spake unto you out of the midst of the fire: ye heard the voice of the words, but saw no similitude; only ye heard a voice.
13 And he declared unto you his covenant, which he commanded you to perform, even ten commandments; and he wrote them upon two tables of stone.
14 And the Lord commanded me at that time to teach you statutes and judgments, that ye might do them in the land whither ye go over to possess it.
15 Take ye therefore good heed unto yourselves; for ye saw no manner of similitude on the day that the Lord spake unto you in Horeb out of the midst of the fire:
16 Lest ye corrupt yourselves, and make you a graven image, the similitude of any figure, the likeness of male or female,
17 The likeness of any beast that is on the earth, the likeness of any winged fowl that flieth in the air,
.
