  1. i guess you are looking for this

    add_attachment

    and

    delete_attachment

    example:

    add_action('add_attachment', 'attachment_manipulation');
    function attachment_manipulation($id)
    {
      if(wp_attachment_is_image($id)){
        //do your own tasks
      }
    
    }
