Removing the custom_image_header from wp_head

I was able to remove this by using
remove_action('wp_head', 'header_uri');

Where header_uri is displayed in the above function you must use the same function name you have used to initialize the function in add_custom_image_header() within your functions.php file.

. example: add_custom_image_header('header_uri', 'admin_header_style');
