Cannot find "rel=author" field in single-post.php

This request is for a blog. I am trying to update the blog so that the coding includes coding rel=author into the ‘about’ page

My goal is to have the blog author’s profile pic show up in google searches, as instructed here:
http://www.virante.org/blog/2012/01/08/how-to-show-your-author-photo-in-google-search-results/

I have been able to complete most of the steps there except one – adding the “rel=author” field in the single-post.php area.

Is this possible? or can it be accomplished in by other means?

Thanks!

The blog is:
