Hi everyone. I'm trying to put the featured image (full size) in the byline for single post pages. Here's the code I am using but it is not working:

<?php the_post_thumbnail('full'); ?>

What am I doing wrong?

Thanks!

You can't use PHP in the theme options. You could add a "New Widget Area" to the byline area and then use a PHP aware widget for your code.

Oh right. I knew that. Thanks for the reminder. Problem solved.
