I just checked and I was able to see all the images in the Knowledge Base article. The issue could be due to your web browser from which you are accessing the page. Some web browsers automatically disable images from loading. Fixing this could be as simple as selecting “Show all images” from the browser’s settings menu.
Further, it’s also worth checking if the device you’re using has security software or extensions that could potentially block images. Again, adjusting the settings to allow images should correct the issue. You could also try clearing the cache and cookies from your web browser and then reload the page.
Hope this helps!
