Display author gravatar rather than thumbnail
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,
