 * PHP Error:
 * > Warning Cannot modify header information – headers already sent by (output 
   > started at /home/iac/public_html/new/wp-content/plugins/image-cleanup/image-
   > cleanup.plugin.php:151)
 * Function column_css echoes an in-line <style> on ‘admin_init’ hook (!) – before
   headers are sent. It prints the style before <doctype> is even declared.
 * Try instead to hook on ‘admin_enqueue_scripts’:
 *     ```
       add_action( 'admin_enqueue_scripts', array ($this, 'img_clnup_admin_style' ));
       function img_clnup_admin_style(){ 
         wp_enqueue_style('img_clnup_admin_style', IMGCLNUP_PLUGIN_URL . "img_clnup_admin.css");
       }
       ```
   
 * (or at least print/echo it on the page – safely inside the html body)
 * Salut!
