dude, this is an absolute and complete scam. I get emails all the time from people saying the same thing. "I liked your profile, I hope you like my pics, etc."
Just to make sure, have her send you something physical of value before you even consider spending a nickel on her.
even if you don't find her on the "scammers network" or whatever, don't fall for it.
At the very least, get a voice/video chat over skype with her. chances are she'll never go for it, and there's a good chance "she" might even be a guy sending fake photos, and asking for money.
Sadly, men get taken in by this all the time. She likely has sent the same email to hundreds of other guys, hoping one of two of them will send her a few dollars (or rubles).
Remember PT Barnum's famous quote "sucker born every minute" is just as true today as it was back then.
