Were any of the pics nudes? If she sent any pics to you, they are child porn if she's really under 18 (not 17, 18! Yes, you can legally look at, touch, and have sex with a 17-year old, but if you take a picture of her, you're breaking the law!)

If you sent a nude pic of yourself to a minor, that is a crime as well.

If none of the pics were nudes, then no laws were broken here, and her threats are just empty threats. If she had said she was 14 and you had texted her, "lets have sex", you could be busted for attempting to have sex with an underage person. But since she represented herself as being of legal age, and you didn't try to meet her in person, no harm, no foul.

Whatever her age is, she sounds like a lot more trouble than she's worth.
