getting closer

PHP Code:
$lc_text .= '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), 'cPath=' . (($_GET['manufacturers_id'] > 0 and $_GET['filter_id']) > 0 ?  zen_get_generated_category_path_rev($_GET['filter_id']) : ($_GET['cPath'] > 0 ? zen_get_generated_category_path_rev($_GET['cPath']) : zen_get_generated_category_path_rev($listing->fields['master_categories_id']))) . '&products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION) . '</div>' .
        '<div id="barcodeimage"><IMG SRC="barcode.php?barcode=' . $listing->fields['products_ean']; '&width=400&height=200"></div>'; 
but it is ignoring the size part of url

&width=400&height=200

so image is now in correct place but wont generate barcode because it needs size part of image

thanks for help so far
