[OpenID] Profile image sizes

[Chris Messina]

I agree, Simon, a retract that part of my suggestion.

I'll be writing up more about this soon, but i'm leaning towards
something that works with the existing hcard microformat:

<span class="vcard"><a href="http://link.to/images/avatar.png"
rel="avatar"><img src="http://link.to/images/avatar_thumb.png"
alt="Avatar for Chris Messina" title="Chris Messina" class="photo
fn"/></a></span>

Generally the idea is that you'd still use the hcard photo object as
the avatar, but if there is a link to a full size image denoted by
rel="avatar" on someone's default hcard or profile page, then defer to
that image.

How does that sound? That therefore allows the avatar file to exist
anywhere and be any type of file (which I agree is important) and also
allows for the use of a URI designation for the avatar instead of some
made-up convention (as Martin also pointed out).
