I'm attempting to modify the RSS feed and only need the author image URL
<?php userphoto_the_author_thumbnail(); ?>
returns
<img width="80" height="80" class="photo" alt="author name" src="http://domain.com/wp-content/uploads/userphoto/author.name.jpg"/>
What returns
http://domain.com/wp-content/uploads/userphoto/author.name.jpg
??
Thanks for any assistance you can offer.
