Checkout product images are missing

-- url of the page with the problem -- : aroma-care.co.il/index.php/en
-- HikaShop version -- : 2.2.3
-- Joomla version -- : 3.3.6

Hi,

I'm working on a client's site which I didn't built. It seems that the images for the products in the checkout page are mostly missing. When I've inspected the code I've found out that each image is being looked for in a different folder under "/media/com_hikashop/upload".
I get many different folders:
/media/com_hikashop/upload/thumbnail_99x200/
/media/com_hikashop/upload/thumbnail_521x600/
/media/com_hikashop/upload/thumbnail_682x500/
And so on...
Usually this folder do not exist and if they do they are usually empty. Thous the missing images.

In the product pages, all of the images are being pooled from the same directory which is "/media/com_hikashop/upload" and are presented o.k.

How can I please change the code so the checkout images will be pooled from the same base folder?

Thank you in advance,

Guy.

Well, tried to over ride the old cart php file with a new one and that broke the page.
I guess there are some template overrides that make this more problematic.
The client decided to let it go for now. Thank you for your kind help.
