If you have thumbnails for your blog theme and you have no images in the post, but you have YouTube Videos, then you can pull the YouTube Video Thumbnail using this PHP function.
function kish_update_video_thumbnail($youtubeurl, $postid) {
if(strlen($youtubeurl)) {
//$pattern="/[\?&]v=([^&#]*)/";
$pattern="/http://www.youtube.com/v/([w-]{11})/";
preg_match($pattern, $youtubeurl, $matches);
$thumb="http://img.youtube.com/vi/".$matches[1]."/0.jpg";
update_post_meta($postid, 'video_thumb', $thumb);
}
}
The commented pattern can be used if you are using the video URL. This will update the post_meta with the thumb URL
