Not perfect, but will work.

Open newthread.php, find:

PHP Code:

    // check max images
    if ($maximages!=0) {
      $parsedmessage=bbcodeparse($message,$forumid,$allowsmilie);
      if (countchar($parsedmessage,"<img")>$maximages) {
        eval("standarderror(\"".gettemplate("error_toomanyimages")."\");");
        exit;
      }
    } 


Below, add:

PHP Code:

    if(strstr($message,'[img]')) {
      eval("standarderror(\"".gettemplate("error_noimagesnewreply")."\");");
      exit;
    }
    if(strstr($message,'[IMG]')) {
      eval("standarderror(\"".gettemplate("error_noimagesnewreply")."\");");
      exit;
    } 


Then, ADD a template called "error_noimagesnewreply" with this content:

You cannot use the [img] code with a new thread!

That would work.
