How do you let a non-friend tag you on facebook?

[Daniel]

I met this person at a national park, before we left we took a picture together with her phone. Instead of friend requesting me, I let her tag me in the picture. She gave me the phone. When tag clicked tag I went through a list of people with my name and clicked on my profile. That picture was tagged with my name not in a hyperlink, but in black letters.

I assumed that when I got home, that picture would be tagged and on my wall. But instead there was NOTHING. I have no idea what her name was, and she didn't see my profile picture. How can I find her?
