CSS and osCommerce fix

I have made a modification to the product_listing module in oscommerce to display an image when a certain requirement is met. But for some reason it doesnt show in the correct place. I need the code modified to work correctly. I beleive its a CSS issue, but could also be a html issue. You can see the image working correctly on this page: <[login to view URL]> The image is the green "Save 20%" banner in the top left corner of the product. I am trying to make this work on an older version of oscommerce but it wont work correctly. The site for it to be fixed on is [login to view URL]
