if you change the sql query in manbox.php

like this

$manufacturers_query = tep_db_query("select manufacturers_name, manufacturers_id, manufacturers_image from " . TABLE_MANUFACTURERS . " where manufacturers_image not like '' order by manufacturers_name" );

then you see in the box only the manufactors which have an logo uploaded..

you have only add to the normal query the where manufacturers_image not like ''
code

see you
