So I have a mailchimp email that goes out and shows the latest posts that have been made on the site. The users on the site all have gravatars and I want to include that in the rss feed so that I can point the mailchimp image reader to them.
I have tried using snippets like:
<?php echo get_avatar( get_current_user_id(), 48 ); ?>
<?php echo get_avatar( get_author_email(), 48 ); ?>
and adding that to the rss template in /wp_includes (I would love to do it in functions.php but honestly I just want it to work for this one site so I don't care how I get it done).
It's curious because when I do searches I can only find people trying to figure out how to remove it instead of insert it... I am at a loss.
