Barcode image on inventory template with variable field

Barcode image on inventory template with variable field

Hi,

I want to show a barcode for every product on a sales or quote inventory template.

For this, I want to insert an img with the following source: https://www.barcodesinc.com/generator/image.php?code=Your Text&style=197&type=C128B&width=167&height=50&xres=1&font=3

I need to replace code=your text with a barcode field from products (products.product code). How do I achieve this?

Thnks, Maarten
