[Plugin: WordPress Related Posts] Support Intext Images

Hi,

after installation I made an update to your code.
If no thumbnail is attached or defined it tries to parse an image included using an “img” tag

function wp_rp_get_post_thumbnail_img($related_post) {
//...

	$postContent = $related_post->post_content;
	if (preg_match('/.*<img.+src=["]([^"]+)["].*/i', $postContent, $imgMatch)) {
		$img = '<img src="'. $imgMatch[1] . '" alt="' . esc_attr(wptexturize($related_post->post_title)) . '" />';
		return $img;
	}
//...
}

It would be nice if you add this to your code.
