I'm gonna have to go ahead and say that the majority of answers given to you so far will not result in you getting this guy. Gary999 definitely is on the right track but don't listen to the last part about the girls in this guy's pictures.
Listen, you have no idea what type of girl this guy is looking for. Who cares what the girls in his facebook pictures look like. I have tons of facebook pictures with girls. Many I've never even been interested in. it's just a picture I took cause I saw them out at a party or a bar and we know each other so we snapped a photo (the pictures have no say on his type). I generally consider myself a brunette guy, however, I've dated girls who are blondes. I'm sure if your just act your cool, outgoing, friendly, fun self with this guy, you'll be fine. I'm not guaranteeing that this turns into a relationship but hey, what do you have to lose? I mean if you can show this guy the best side of you, and he isn't interested still, then there's nothing you can do. I rather find out someones not interested in me rather than sit around and just wonder. At least I can move on and find someone else to go after.
You'll never know his type until you get to know him more. You'll never know if he's interested in you unless he knows your interested in him. Of course you can sit around with your fingers cross and hope by chance he is into you and makes a move, but why wait for that to happen. Show him your interested. Don't fear rejection. View rejection as a healthy thing. Once you lose that fear, you will be able to go after whoever you want. Rejection just tells you to move on with your life and stop losing sleep over a waste.
I would make more of an effort to hang out with him. Next time you see him, make a comment about you guys hanging out sometime soon. Grab his phone and say, "here let me give you my number, shoot me a text." Right there you are showing him you are interested. You want him to have your number, you want to hang out sometime, and you want him to shoot you a text. Then you'll have an idea if he is interested if he texts you or not. If he doesn't text you, then that might be a sign he isn't interested but I wouldn't give up yet. Next time you see him, give him a little guilt. Joke around and say, you know I've been a mess sitting around for the last couple days/weeks waiting for a text from you. See how he responds. Watch his body language.
If still nothing comes about, then just move on. Don't stress on it. But I think if you show your interest you'll be able to get some good signs back if he is interested back. Just completely block out all the thoughts of what you think MIGHT be his type or all the images of the girls in facebook. All that stuff doesn't matter. What matters is how you act around him and handle the situation.
