Add rel nofollow to featured image

Hi there,

try this PHP snippet:

add_filter( 'post_thumbnail_html', 'db_post_thumb_nofollow', 10, 3 );
 
function db_post_thumb_nofollow( $html, $post_id, $post_image_id ) {
 
  $html = '<a href="' . get_permalink( $post_id ) . '" rel="nofollow" >' . $html . '</a>';
  return $html;
 
}

Thanks David,

The featured image link in category nofollow, but this code insert future image link in in single post too

Try:

add_filter( 'post_thumbnail_html', 'db_post_thumb_nofollow', 10, 3 );
 
function db_post_thumb_nofollow( $html, $post_id, $post_image_id ) {
  if ( is_single() || is_page() || is_front_page() ) {
    return $html;
  } else {
    $html = '<a href="' . get_permalink( $post_id ) . '" rel="nofollow" >' . $html . '</a>';
    return $html;
  }
}

featured image of Homepage still have link
