I thought most email clients block third party images by default? Certainly Outlook, Thunderbird, and K9 do. This must skew those results somewhat.

  I think I saw statistics somewhere that most people read their mail via the web interface of their email provider, not via a client, and I don't know whether web clients block remote content loading.
