Png link auto embed(convert)

[BadgerDog]

Ok, for my clarity and so I don't screw it up ...

Is this the code I need to use to create the plugin discussed?

$post['pagetext'] = preg_replace('/\[URL\](http.*?\.(png|jpg|gif))\[\/URL\]/i', '', $post['pagetext']);
if ($content != $post['pagetext'])
{
global $vbulletin;
$pagetext = $content;
require_once(DIR . '/includes/class_bbcode.php');
$bbcode_parser = new vB_BbCodeParser($vbulletin, fetch_tag_list());
$post['pagetext_html'] = $bbcode_parser->parse($pagetext, $post['forumid'], 1);
$post['pagetext_html'] = html_entity_decode($post['pagetext_html']);
}

Thanks ..

Regards,
Doug
