Attachment Watermark (Certain forums)

[mk craig 42]

Is it possible to only add a watermark to attachment if it was posted in certain sections?
There are 3-4 sections on the forum that I DO NOT want attachment watermarks on, however the rest of them.

Is this possible:

This is the product for my current one:

PHP Code:

$tempimage='';
$referers_count=0;
$referers=array();
if($vbulletin->options['watermark_referer']) {
    $referers=explode(',',$vbulletin->options['watermark_referer']);
    if(empty($_SERVER['HTTP_REFERER'])) {
        $referers_count=1;
    }
    else {
        str_replace($referers,'',$_SERVER['HTTP_REFERER'],$referers_count);
    }
}

if(!isset($_SERVER['HTTP_RANGE'])
    &&in_array($extension,array('jpg','png','gif'))
    &&$attachmentinfo['dateline']<TIMENOW-$vbulletin->options['watermark_days']*86400
    &&(!$referers||($referers&&!$referers_count)))
{
    if($vbulletin->options['watermark_thumb']&&empty($vbulletin->GPC['thumb'])) {
        $clearfname = DIR.'/'.$vbulletin->options['cleargifurl'];
        if( file_exists($clearfname) && $fp2 = fopen($clearfname,'rb') ) {
            header('Content-Length: '. filesize($clearfname));
            header('Content-type: image/gif');
            @fclose($fp);
            $fp = $fp2;    
            $lastbyte = filesize($clearfname)-1;    
        }        
    }    else {        
    
        $wm_t = @imagecreatefrompng($vbulletin->options['watermark_path_top']);
        $wm_b = @imagecreatefrompng($vbulletin->options['watermark_path_bottom']);
                    
        if (strtolower($extension) == "gif") {
