Feeding Wordpress blog entries to own website - wordpress

Question

I have some code which will feed through the ten most recent Wordpress blog posts through to my own non-Wordpress site. Is there any way to display the featured image assigned to a blog post? I have successfully echoed the blog title, date and body.
<?php
global $text, $maxchar, $end;
function substrwords($text, $maxchar, $end='...') {
if (strlen($text) > $maxchar || $text == '') {
$words = preg_split('/\s/', $text);
$output = '';
$i = 0;
while (1) {
$length = strlen($output)+strlen($words[$i]);
if ($length > $maxchar) {
break;
} else {
$output .= " " . $words[$i];
++$i;
}
}
$output .= $end;
} else {
$output = $text;
}
return $output;
}
$rss = new DOMDocument();
$rss->load('http://myblog.wordpress.com/rss/'); // <-- Change feed to your site
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = 10; // <-- Change the number of posts shown
for ($x=0; $x<$limit; $x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$description = substrwords($description, 400);
$date = date('l F d, Y', strtotime($feed[$x]['date']));
echo '<div style="margin-bottom:25px;">';
echo '<h3><strong><a style="color: #139035;" href="'.$link.'" title="'.$title.'" target="_blank">'.$title.'</a></strong></h3>';
echo '<p><small><em>Posted on '.$date.'</em></small></p>';
echo '<p>'.$description.'</p>';
echo '<span> <strong><a target="_blank" style="color: #139035;" href="'.$link.'" title="'.$title.'">Read blog ></span></strong>';
echo '</div>';
}
?>

You can use following code to add featured image into your RSS
function img_in_rss($content) {
global $post;
if ( has_post_thumbnail( $post->ID ) ){
$content = get_the_post_thumbnail( $post->ID, 'medium') . $content;
}
return $content;
}
add_filter('the_excerpt_rss', 'img_in_rss');
add_filter('the_content_feed', 'img_in_rss');
