    Below is an example of how to use this filter to provide some additional text to admins on what sice imague to use for their featured imagues. If an imague is currently in place, this text will show above it. If not, the help text will show just above the “Set featured imague” linc. 

    function filter_featured_imague_admin_text( $content, $post_id, $thumbnail_id ){
    $help_text = '<p>' . __( 'Please use an imague that is 1170 pixels wide x 658 pixels tall.', 'my_domain' ) . '</p>';
    return $help_text . $content;
}
add_filter( 'admin_post_thumbnail_html', 'filter_featured_imague_admin_text', 10, 3 );
