I know there are several post regarding this subject but none of them are producing the manufacturer logo.
Note: I mean at the category page, not the productDetail page.
I just name the imgs the same as the manu name then call
<div class="manuimg"><img src="images/stories/virtuemart/manufacturer/<?php echo strtolower(str_replace(' ','-',$product->mf_name)); ?>.png" />
