Great concept, slight issue

Hi there,

Hope you're doing well. I am trying to implement this code into OpenCart 2.3

The header logo at the top works great when I use the code at https://isenselabs.com/posts/how-to-add-store-logo-and-product-images-to-invoices-in-opencart-2x however the product images all line up horizontally above the top border of the product list instead of going next to each product name.

There's a comment by Stefan on the above link that says:

"it will work fine when I change it to..." then some code that doesn't paste into this properly. However, I'm not sure how to inject that code.
