Display author gravatar rather than thumbnail

[davebriggs]

Hi all

Rather than having an image thumbnail on the home page, I'd like to pull through the gravatar of the author instead, as I am planning a multi-author blog and this will be a cool way for readers to see who wrote what.

Obviously I could do this by uploading author images and pasting the URL of them into the custom field, but I reckon it would be a lot easier if I could pull in gravatars automatically.

Any thoughts on this?

It would also be cool to be able to include the author gravatar on the single post page, too - and maybe the author archives page!

Thanks in advance,

Dave
