add to cart image and input field

[tonkali]

hi all,

just cant seem to figure this one out. On the product info page I have substituted the "Add to Cart" text with an image but I'm having trouble aligning it with the input field (see here).

From the tpl_product_info_display.php, here is the

<!--bof Add to Cart Box -->
<?php
if (CUSTOMERS_APPROVAL == 3 and TEXT_LOGIN_FOR_PRICE_BUTTON_REPLACE_SHOWROOM == '') {
  // do nothing
} else {
?>
<?php
    $display_qty = (($flag_show_product_info_in_cart_qty == 1 and $_SESSION['cart']->in_cart($_GET['products_id'])) ? '<p>' . PRODUCTS_ORDER_QTY_TEXT_IN_CART . $_SESSION['cart']->get_quantity($_GET['products_id']) . '</p>' : '');
            if ($products_qty_box_status == 0 or $products_quantity_order_max== 1) {
              // hide the quantity box and default to 1
              $the_button = '<input type="hidden" name="cart_quantity" value="1" />' . zen_draw_hidden_field('products_id', (int)$_GET['products_id']) . zen_image_submit(BUTTON_IMAGE_IN_CART, BUTTON_IN_CART_ALT);
            } else {
              // show the quantity box
    $the_button = zen_image_submit(BUTTON_IMAGE_IN_CART, BUTTON_IN_CART_ALT) . '<input type="text" name="cart_quantity" value="' . (zen_get_buy_now_qty($_GET['products_id'])) . '" maxlength="6" size="1" /><br />' . zen_get_products_quantity_min_units_display((int)$_GET['products_id']) . '<br />' . zen_draw_hidden_field('products_id', (int)$_GET['products_id']);
            }
    $display_button = zen_get_buy_now_button($_GET['products_id'], $the_button);
  ?>
<?php if ($display_qty != '' or $display_button != '') { ?>
    <div id="cartAdd">
    <?php
      //echo $display_qty;
      echo $display_button;
            ?>
          </div>
  <?php } // display qty and button ?>
<?php } // CUSTOMERS_APPROVAL == 3 ?>
<br /><br />
<!--eof Add to Cart Box-->

<!--bof Attributes Module -->
<?php
  if ($pr_attr->fields['total'] > 0) {
?>
<?php
/**
 * display the product atributes
 */
  require($template->get_template_dir('/tpl_modules_attributes.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_attributes.php'); ?>
<?php
  }
?>
<!--eof Attributes Module -->

I've looked in the tpl_modules_attributes.php file but there doesn't seem to be anything there to help. desperately seeking a clue.
