Add the following to your child-theme‘s functions.php:
function column_id($columns) {
$columns['colID'] = __('ID');
return $columns;
}
add_filter( 'manage_media_columns', 'column_id' );
function column_id_row($columnName, $columnID){
if($columnName == 'colID'){
echo $columnID;
}
}
add_filter( 'manage_media_custom_column', 'column_id_row', 10, 2 );
