Sometimes you may want to feature the post author in separate space inside the post like about author box, Here is a simple PHP code snippet which returns the current post authors Gravatar with a desired image size.
<?php echo get_avatar( get_the_author_email(), '80' ); ?>
Use the above PHP snippet inside post loop (single.php) to automatically retrieve post author gravatar. In above code the gravatar thumbnail size is 80*80px, Just change the parameter to increase or decrease the size (1px up to 2048px).
