 * Hi i’m using 2.9.x version of wordpress and the new thumbnail funcion.
 * To use it i set my function.php in this way :
 *     ```
       <?php
       if ( function_exists( 'add_theme_support' ) ) { // Added in 2.9
       	add_theme_support( 'post-thumbnails' );
       	set_post_thumbnail_size( 270, 100, true ); // Normal post thumbnails
       	add_image_size( 'single-post-thumbnail', 500, 300, true ); // Permalink thumbnail size
       add_image_size( 'related-post-thumbnail', 100, 100, true ); // Permalink thumbnail size
       }
   
       php?>
       ```
   
 * my question: i need another thumbnail of different dimension to insert it in
 *     ```
       <? $quantipost = '10'; // totale dei post da mostrare ?>
       <h2> <?=$quantipost; ?> Post a caso</h2>
           <ul>
             <?php
        $rand_posts = get_posts('numberposts=$quantipost&orderby=rand');
        foreach( $rand_posts as $post ) :
        ?>
             <li><a href="<?php the_permalink(); ?>">
               <?php the_title(); ?>
               </a></li>
             <?php endforeach; ?>
           </ul>
       ```
   
 * is it possible?
 * when i put <?php the_post_thumbnail( ‘related-post-thumbnail’ ); ?> in that funcion
   the pic that is showed is always the same, how can i solve this?
    thanks.
