    if(!$fp)
    {

        fputs($fp, "get /scripts/online.dll?icq=$uin&img=5 http/1.0\n\n");  
        $do = yes;  
        while(!feof($fp))
        {
            $line = fgets ($fp,128);
            $do = ($do == yes)?yes:(eregi("^gif89", $line))?yes:no;
            //echo $line;
            
            if($do == yes)
