*Modification Name: Thumbnail                                                *
******************************************************************************
*      Description: Adds a tag [thumb] that allows users to post images that *
*                   are larger than the topic page tables without stretching *
*                   the tables/page. It DOES NOT reduce the size of the down *
*                   load. When you click on the thumbed image the fullsize   *
*                   image opens in a new window.                             *

Open ubb_lib.cgi and look for...

if ($_[1] eq 'ON') {
			$match++ if $_[0] =~ s/(\[IMG\])(\S+?)(\[\/IMG\])/&imageize($2)/eisg;
			$match++ if $_[0] =~ s/(\[IMAGE\])(\S+?)(\[\/IMAGE\])/&imageize($2)/eisg;

Replace that with
