no images on the ad

Hi,

do you mean to remove the gallery field from the Classifieds Publish form?

If so then you can do that either with the Custom Fields extension or add the below code in your theme functions.php file

add_filter( "adverts_form_load", function( $form ) {
  if( $form["name"] != "advert" ) {
    return $form;
  }
  foreach( $form["field"] as $k => $field ) {
    if( $field["name"] == "gallery" ) {
      unset( $form["field"][$k] );
    }
  }
  return $form;
} );
