Images don't show up when converting HTML to PDF

I am trying to convert an HTML file to PDF using YARG, but the images (stored locally) don’t appear in the PDF. Accordingly to your article “Yet Another Report Generator?” (Yet Another Report Generator? – Jmix) it is possible to include images (“Ability to use HTML layout and insert/embed images”), but I’ve looked in the documentation and haven’t found a way to make it work.
