I also tested it on both the February release version and the latest March release version of Power BI Desktop, and the image url can be shown on the table visual if I change the Data Category into image-Url.
Could you share a sample pbix file which can reproduce the issue? So that we can help further investigate on it. You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading.
i also use the latest March release version of Power BI Desktop,
unfortunately i can not see my images with tables or multi-card ,still URLs!!
I must add a filter to my report and choose between the URLs then i can see the Images not URLs (but just with Imageviewer) ?
So with a table or multi-card did not work!
In the photo you can see a table , an imageviewer and a filter ,i have a column with 'id' name and another one with 'AnswerImages1' name.
Sorry i dont know how to mask data i will see and then i will upload a pbix file , if i could not find the solution.
Thanks for Help
In order to have the solution to this question, I give the answer:
You have to select the field and go to the Modeling tab, select Data Category and set it to Image URL.
The visuals tha support image as an url are: the Table visual and the Card visual.
