The following can happen:
- You make a site for a customer
- You insert some comments that your customer provides.
- Gravatar uses the admin email instead of the comment author email.
How do you get a gravatar image for the comment email instead of the author email?
You need to write a filter function. the
get_avatar filter passes the img code as first param, and the id of the author(you) or an emailaddress as the second.
