How do i get this Grl??

I got a missd call frm dis grl at 3am, as she randomly dialled my number. I called next day and we strike a conversation. She is from school i m frm coll. and she has a bf too. And i have an impression that dis grl is promiscuous that's why she is intrstd in a toal stranger even after already having a bf. For two weeks i called her every sunday. she told me abt her hobbies, her family and stuff. Now she insists that she needs to see my photo first and then meet me(if interested). Then i just asked her that what did she look like and what clothes does she like to wear and she hangs up the phone. I was startled. I did not call her back again. It's been 1&1/2 week. now i think i should email her my pic. But i m confused is it dangerous to email her my pic and she may misuse it or sumthing?? What exctly should be my next step so that i get her pic and if she is fine i get to sleep with her?? What is a clever way to deal with tis situation??
