Actually I disagree, saying that she took photo
with you because she is interested or at least interested to
further the relationship a little. This is a misconception. This,
IMO, is merely goodwill and goodwill is not to be mistaken for
anything else. I rather tell you this, than to instill false hope
and you become complacent.
If you wanna woo her and since you know what's your flaw, if you
don't work to improve it, you shall see yourself losing
to yourself and ulimately a potential relationship
with her. 
Cheers
