I'm with Austerus on this one... only since its an online only thing I would seriously consider blocking her (if its even really a her) completely from your email etc especially considering her issues.

Heck when she said you could be her submissive despite the two of you never having so much as met yet face to face makes me think something is fishy or someone is living in fantasy land.

In so much as pictures and such go, I can't stress enough the importance of keeping one's personal information private, addresses, phone numbers, one's location (including city and state) recognizable face pictures and or any other identifiable information is simply not a good idea to hand out online to people you have no possible way of ever knowing let alone trusting with such things.
