Talk and get to know each other as well as you can and believe only what you feel in your heart is true. Sometimes even that can lead you astray so also trust your better judgment.
There is no rush so be sure you want to share any of your personal information before you actually do. You must have full trust in anyone you want a relationship with. If for some reason it doesn't feel right it probably isn't. Don't share anything that can come back to bite you in the ass like you address, phone number, etc. Right now you don't even know if the pictures she sent you are actually her or if, in fact, it is actually a her to begin with. Proceed with caution until you are sure and then still be careful.
Once all is in place discuss what you want out of a relationship and see if your interests are mutual.
