I'd say talk to her for why she lied to you. Then if you still want to, dump her (carefuilly). If a girl like her is too ashamed of the way she looks (becuase she's fat) that she has to hide herself behind people; and that she had to deceive you by using camera angles, then she still has issues that need to be resolved (with you or by herself). This is one of the reasons why I don't do online dating. I've had girls (really hot ones too) e-mail me for a date but I turned them all down.
I understand that it can be hard to lose weight for some people. But for most that can easily do it without too much struggle, it's no excuse to hide it since it can make other people question them, and think of them differently. Obesity/fatness is a health issue; but with todays society, it's often treated as a lifestyle, people etc.
Thoes are my two cents. You can ignore it, disagree, whatever I don't care.
