What version of Tableau Server are you using? Looks like there was a bug causing that issue that was patched in Tableau Server 9.1.5: 9.1.5 | Tableau Software
Defect Note: In Tableau Server, custom shapes and images on dashboards appeared blurry in browsers after publishing.
If upgrading Tableau Server doesn't solve the issue - I'd suggest reaching out to Tableau Technical Support.
Hope this helps!
Thanks a lot for your help. We are not using Tableau Server, we are using Tableau Online.
Actually the pictures are blurry on Tableau desktop but when we get online using Tableau Online the pictures are not blurry anymore but just way too big for the display box (we can only see a quarter of the picture). It is exactly the same issue as Re: Need Help with Resizing Web Page Image in Dasbhoard but the solution proposed in this post is for people using Tableau Server and we are using Tableau Online ... Any ideas?
Thanks a lot.
Hi guys could i have know your problem What version of Tableau Server are you using ?
We are using Tableau Online. Any ideas?
If this is with Tableau Online and the image works fine in Tableau Desktop, it may be time to submit a case to Tableau Technical Support.
I did that but they did not have the solution ...
