Change default wordpress thumbnail image in list

Hello

Try this :

add_filter( 'bawmrp_no_thumb', 'change_bawmrp_no_thumb' );
function change_bawmrp_no_thumb( $thumb ) {
  return 'https://mysite.com/new-thumb.jpg';
}

you can paste this where you usually write you tips (functions.php from theme or a mu-plugin)

Thank you so much. It worked like charm. I am going to rate this plugin 5 star. ??
