[Plugin: Cart66 Lite] Problem: Add to Cart and Continue Shopping Button Problems

Hello,

I have set up a custom folder in Cart 66 lite to store all the custom buttons I have made. Almost all of them are showing up correctly after doing this. However, the custom add-to-cart button seems to overlay over the default add-to-cart button. Also, I cannot customize the continue shopping button which you see once you hit the add to cart button. I named this continue-shopping.png and cannot see it. Does anyone know what that should be named? And, how to solve the add to cart issue?

See this page for an example of the issue:

Click on add to cart to see the continue shopping button issue.

Thanks.
