widget - wordpress recent posts show thumbnail -

how can show either small thumbnail of image or featured image, each post in recent posts custom widget

here's code:

<?php  include($_server['document_root'] . $root . 'blog/wp-load.php');  $recent_posts = wp_get_recent_posts(array(     'numberposts' => 3 ));  ?>  <h3 class="divider">recent blog posts</h3> <ul class="listing"> <?php foreach($recent_posts $post) { ?>     <li><a href="<?php echo get_permalink($post['id']) ?>">     <div><?php echo $post['post_title'] ?></div></a></li> <?php } ?>   </ul> 

you can use get_the_post_thumbnail

usage:

<?php echo get_the_post_thumbnail( $post_id, $size, $attr ); ?> 

integrated code:

<?php foreach($recent_posts $post) : ?>     <li>         <a href="<?php echo get_permalink($post['id']) ?>">             <?php echo get_the_post_thumbnail($post['id'], 'thumbnail'); ?>             <div><?php echo $post['post_title'] ?></div>         </a>     </li> <?php endforeach; ?>  

note: enable post thumbnails, current theme must include add_theme_support( 'post-thumbnails' ); in functions.php file. see post thumbnails.
