Hi,
I am trying to update a data viz with new PDFs. This viz worked for years and now I'm having issues.
The PDFs show up in the Tableau Desktop view, but when I publish to Public, I just get a "google is blocking this image" message for each PDF.
Has anyone ever found a work-around or solution to this issue?
The PDFs are hosted on WordPress and each link begins with https:// so the http-https incompatibility isn't the problem.

Hi, Unfortunatelly the site https://www.aei.org/wp-content/uploads/2025/05/alabama.pdf has enforced the security of the website, so you can't embed the content in other webpage:
"Access to fetch at 'https://www.aei.org/wp-content/uploads/2025/05/alabama.pdf' from origin 'https://public.tableau.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."
So, in developer words this means that you can't execute scripts or embed elements into iframes (which are used by Tableau Public).
As a WORKING workaround, you may use an approach to use docs.google.com. Just add the url of the pdf after the url param:
https://docs.google.com/gview?embedded=true&url=https://www.aei.org/wp-content/uploads/2025/05/alabama.pdf

If this post resolves the question, would you be so kind to "Select as Best"?. This will help other users find the same answer/resolution and help community keep track of answered questions. Thank you.
