Triple Images Showing Up

I need your help. I have a set of 18 WordPress sites set up under worldwidedojo.com. I am using your better author bio for all the sites. Every time I update WordPress, I have to edit the /wp-includes/pluggable.php file with this:

// WWD Customization
// $avatar = “<img alt='{$safe_alt}’ src='{$out}’ class=’avatar avatar-{$size} photo’ height='{$size}’ width='{$size}’ />”;
$avatar = the_author_image();
} else {
// WWD Customization
// $avatar = “<img alt='{$safe_alt}’ src='{$out}’ class=’avatar avatar-{$size} photo’ height='{$size}’ width='{$size}’ />”;
$avatar = the_author_image();
}

I usually update the PHP file after every update of WordPress, but this time the wordpress update did not overwrite my customization but I am still getting extra images at the bottom of the page. Can you tell me how to fix this?

See the bio at the bottom of the following page and at the very bottom of the page you will see the extra images.
