You have to add this to your product.php otherwise it won't work.
Code:
$manufacturer = func_query_first("SELECT manufacturer,image,image_type,manufacturerid FROM $sql_tbl[manufacturers] WHERE manufacturerid='$product_info[manufacturerid]'");
$smarty->assign("manufacturer", $manufacturer); {
}
$manufacturerid = func_query_first("SELECT manufacturerid FROM $sql_tbl[products] WHERE manufacturerid='$product_info[manufacturerid]'");
$smarty->assign("manufacturerid", $manufacturerid);{
}
right above
Code:
$smarty->assign("product",$product_info);
by default the manufacturer image is not called as a variable. I did it on my site and it works great.
good luck
