Add to Cart Buttons add-on missing image

Hello Zenners,
I have recently added the Add to cart buttons add-on (located here http://www.zen-cart.com/index.php?main_page=product_contrib_info&cPath=40_62&products_id=1548
I followed the instructions to a tee but I am not seeing the buttons in my Product Listings pages. You can see what I mean by going here http://www.klkreflectiveimages.com/shop/index.php?main_page=index&cPath=7
It's driving me crazy since I know that the button file has been uploaded. I am using an override and have placed the button image in my public_html/includes/templates/TEMPLATE_NAME/buttons/english/button_quick_add_to_cart.gif directory as instructed, but still no joy.

Please, if anyone can lend a hand... I'm almost there :)

In your source, that image is represented by BUTTON_IMAGE_QUICK_ADD_TO_CART rather than the image name, so I would guess you put the button_names.php file in the wrong folder or it's missing or corrupt.

Haha right you are Stevesh!
I had uploaded my button_names.php file to includes/languages/english/ instead of /includes/languages/english/MY_TEMPLATE

Thanks so much for your help! You rock!
