    im trying to get a random hero image with
 * $hero_image = query_posts(array(‘post_type’=>’hero_image’, ‘orderby’=>’rand’,’
   posts_per_page’=>1));
 * the issue is that a lot of times on reload it uses the same random image. is 
   there
    a solution to make sure not the same image is getting used after page 
   refresh?
 * thanks

 * You might use the get_option() and update_option() functions to keep track of
   the last hero, something like this (UNTESTED):
 *     ```
       $args = array (
          'post_type' => 'hero_image',
          'orderby' => 'rand',
          'posts_per_page' => 1
       );
       $last = get_option('last-hero');
       if ($last) $args['post__not_in'] => array($last);
       $hero_image = query_posts($args);
       if ($hero_image) update_option('last-hero',$hero_image[0]->ID);
       ```
