PDF generation, image doesn't show

Hello, I did adapt the code in the ticket general folder so I could use my own logo in the generated pdf:<td width="50%" style="text-align:right;"> <img width="150px" src="http://kiezegemkermis.be/wp-content/uploads/2021/06/gen_logo.png" /></td>When I go to the url of the image directly I can see the image, but in the pdf itself it shows as a red cross: How can I show my own image?Grts,Koen
