Need help altering a piece of code

Hi all,

I posted this on vbulletin.com, only later to discover this renewed site

Hopefully someone has an idea here with the following:

I would like to alter the code in admin/functions.php
which replaces [img ]xxxx[/ img] with <img scr= > code.

The original code is:

PHP Code:

if($dobbimagecode and ($bbuserinfo[userid]==0 or $bbuserinfo[showimages])) {
      // do [img ]xxx[ /img]
      $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<img src=\"\\5\" border=\"0\" alt=\"\">", $bbcode);
} 

What I would like to do is (described in general):

PHP Code:

$image_size = getimagesize("-- the URL inbetween the img vbcode --");

if ($image_size[0] > '120') {

      $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<a href=\"\\5\" target=\"_blank\"><img src=\"\\5\" border=\"2\" width=\"120\" alt=\"Click image to view in full size\"></a><br><font face=\"Verdana\" size=1>(Click image for full size)</font><br>", $bbcode);

} else {

      $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<img src=\"\\5\" border=\"0\" alt=\"\">", $bbcode);

} 

In other words, I want to resize images larger than a certain
width into thumbnails and I know how to do it, except I don't
know how to extract the image's URL for the 'getimagesize'

Help would be appreciated. Right now, I'm using the thumbnails
by default, however it is giving a width='120' even to external
smilies which are usually 10 times smaller than that

Thanks,

Bira
