Hello from a fellow LaTeX enthusiast.

Out of curiosity, how do you handle external assets (e.g., images [1])?

Extending the retailer example - suppose such company would further like to include a thumbnail for each product in a receipt. Or, extending the inspection example included in the support section, suppose the sender wishes to include a blueprint or an external document. How should they proceed?

Some questions in anticipation. What if it is not possible to store the whole catalog locally for a given receipt template? What if catalog items are regarded as sensitive information for the company?
