Why does he want more picture of me?

Well, the comical answer is:
I have no idea. Send some naughty pictures to my phone and I'll figure out why he wants more.

The more serious answer is:
He almost certainly wants to see you/your pictures because he's attracted to you. He wants to look at you. I think that much is obvious.
The reason why he constantly wants more pictures is probably a derivative of that. Pictures aren't very satisfying. Have you ever watched someone sitting still? It isn't interesting. A picture conveys that you are attractive, but you can't watch, feel, or interact with a picture.
Think of it like chocolate. You can sniff something that smells chocolaty, and it's great, but that's not what you really want out of the chocolate so you aren't satisfied. The same way, he can look at your picture and it's great, but he wants more than just a still image of you. Since he can't have more (at least not when you two are in different places texting), he isn't satisfied and at least wants more pictures.

I hope that is clear. If it isn't, let me know and I can give you some different analogies or try to rephrase it.

I can tell from your pic you look pretty good. you being a girl you know that you can take some pics that don't quit turnout the way you want them to, say this pic you sent him might have been 1 of those. See this guy has friends that he's going to want to show a good pic of the girl that he's been talking 2 so he ask you 4 another 1 to show your true good looking self.

This guy is pretending he has a girlfriend. I believe you guys are not in that status. am I right? He likes you, that's why he want something, anything from you. Normally, the easiest thing a guy can obtain from a girl is pictures. Think about it. Good luck!

You're seriously asking if there could be more to this? Of COURSE there's more to it. He wants a "somewhat naughty" picture of you . . . what else do you think he's after?

Do you two ever get the chance to hang out together, or do you live in different areas? And if you do live close enough to hang out, why aren't you?

BTW.no disrespect here. Just trying to make sure you don't find a fake myspace page for you, filled with your photos. Never know a person't true motives till you ask.

Yes! Be careful! He's probably waxing his carrot to them or showing them to friends. A buddy of mine from HS does that to beat it to, if ya catch my drift. Tell him to take a hike.and if he wants to see your face, use his memory or come see you in person!

I'm probably going to contradict myself. I don't know what to say bout this situation because I had a guy friend who does the same thing too. He always ask for pictures but he said he just like me as friend only. I think he might like you since high school and curious if you still look the same. Also would love to get to know you better or want to date you. Just watch the progress and how this relationship is heading. As long as he doesn't come out and say he likes you, there are going to be ton of answers out there.
