What does it mean if a guy says you look really nice?

Anonymous
I met this guy on Facebook. Never met him before. Anyways, I got a new haircut and put my new picture on Facebook. He usually never really compliments me like this. We just talk about school, and joke around about stupidity. lol. But he said one day in his msg "by the way, you look really nice in your new picture!" What does it mean when I guy says this? Does he really mean it? Is saying this to a girl nicer than saying "you look hot" If a guy cared about you, or liked you, what is the thing they would say that shows that they respect you?
