Cart Module override - Align cart image

Hi all,
i'm trying to do a override on HS Module Cart.
All works fine but i'm not able to create a "good view" about cart image.

This is the override code about module:

<?php
/**
* @package HikaShop for Joomla!
* @version 3.0.1
* @author hikashop.com
* @copyright (C) 2010-2017 HIKARI SOFTWARE. All rights reserved.
* @license GNU/GPLv3 www.gnu.org/licenses/gpl-3.0.html
*/
defined('_JEXEC') or die('Restricted access');
?><?php
if(!empty($html)){
?>
<div class="hikashop_cart_module" id="hikashop_cart_module">
<?php "<img src=\"images/cart_new.png\" width=\"18\" height=\"18\" align=\"middle\" />".$html; ?>
</div>
<?php }

But the result is not good (look attachment file called howisit.png)

I'd like the result shoud be like file howshouldbe.png.

Any help???

ps: i don't want make a language override....

At least kindly tell me what the $ html variable refers to?

However, since this extension does not provide syhis uch an option, it would be advisable to help non-PHP php experts like me to implement it ...

Hello,
thanks for your reply.

Sometimes hikashop team could understand that many people aren't real expert but they are at only the beginning. Understand where is the "problem" is really helpful.

Your indication was really helpful now.

For everybody: My solution is change the CSS code in Hikashops css settings like this:

.hikashop_cart_module:before {
    content: url(../images/cart.png);
    display: inline-block;
    vertical-align: middle;
    margin-bottom: -40px;
    margin-right: 115px;
}
