I'm not thinking of self-signed photos, which as you say don't do much to authenticate the key. I'm thinking of photos signed by trusted parties, PKI style (except that the CA is some trusted person I know rather than Verisign). Of course people can look very similar to each other, but it goes a lot further towards identifying someone than a name.
For one thing, you can't arbitrarily change your appearance, whereas I could if I chose change my name to Wechsler or Giolla Decair and then the only way in which your claim to the name would trump mine would be priority, which doesn't work for John Wilson.
