changing carriage doesn't help, since the pic has already been
taken.
if i were a gal, i would not like the pic to see the light. so
confronting the offender and getting the pic deleted is the correct
thing.
just offer your heartfelt apologies to the girl for being
powerless. i can feel that you're quite stunned by the offender's
actions. at least you got someone to help you and your friend
:)
