Why hasn’t she replied back to me?

So I met this girl online, and we were getting along great. I told her if she can send me pics of her to see how she looks like, and then I send mine, and she hasn’t replied since. One was normal and another one of me shirtless. I’ve been told I’m attractive, countless times, but looks can be subjective. If she doesn’t like me, do you think she’ll at least say that I’m not her type?
