I had the same issue with images that were shown by this template. Hopefully, I found that we can fix this issue by connecting the Jira application to Tableau. Somehow it worked, and images started to be shown properly on the website. You could try this method. Suppose you are wondering about the Jira application or how to connect them properly. In that case, I recommend you visit this site: https://newsupdate.uk/how-to-connect-tableau-to-jira/ with detailed information about the most effective way to connect those applications and prevent appearing any bugs and errors during your work. If you have any questions regarding this topic, please get in touch with me in private messages.
