Need an image showing on a certain categories' products

[Abh]

I have a QR code i want to show on a certain category, let's say Food.

Food category also has subcategories and all these have products inside.

So i need the QR code to show on category/subcats/products.

My QR code is right now in a module installed in the sidebar because that's where it needs to show.

 

PM me a price if you think you can do this or have any questions about the task.
