Hey, it's Lee again.
I am thinking you're not in the right place for see how editing blocks as they are designed to be used within AbanteCart.
The blocks are not hardcoded in the tradition definition as I understand hardcoded.
When you are in the block - click off the SOURCE and see the editor that is used - there an Admin can place whatever language or pics or what ever is desired. This is quite helpful and easy for code challenged folks.
It is quite easy to navigate to these from the Design > Layout , select your page and the section you wish to edit, enable, delete, etc.
