Doesn't matter. It's not yours to take, and from my understanding you haven't even asked the original photographer OR the website if you can use it. You know what copyright is, right? Well, the photographer and/or the website owns this picture and they can sue your ass if they find out about you using it without permission. Because whether you like it or not, it's against the law to claim a photograph or any kind of art to be your own when it isn't.
And no, I can see that the girl in the avatar and the girl in this photograph are not the same person. The fangs are way too small on this girl and the nose isn't sharp enough. I bet the other pictures aren't you, either.
But you claimed it to be you. Remember? So what makes the other pictures any different? I don't believe you. I still think you stole all those pictures, and you don't look anything like the girl in your avatar. If you do, prove it. And you didn't answer the rest of the comment. Sheesh, I wonder why...?
