Bad picture, fine picture... everything is relative, as Einstein said. For instance, I used to think this picture of me is bad, because I look sad and worried...
...but some people have said to me (and no, I don't keep a copy in my wallet): "
oh, how adorable!", "
what big eyes you have!" (and if it is a girl, I answer "
the better to see you with, baby"

), "
you look like a Japanese cartoon!", etc...
