And I completely understood his concerns as I had the same issue with some of the public facing reports that I made, for eg., the US Election report that I had made 1 year back. The images for the candidates were sourced from Wikipedia and certain candidates like George Bush, Donald Trump, etc. are not displayed, because the image URLs are no longer valid.
This is where you can use my workaround to embed the images within the report by converting the images into Base64.
It’s an interesting approach when you need to solve this problem.
