Image url access issue

How to add a image URL using amazon share (or any other source) with open access to everyone to dashboard!!

Hi, you can use a custom visual to display images in your dashboard. The images needs to be publicly accessible. For more information, please see here: Using custom visual content in Amazon QuickSight - Amazon QuickSight

If you are looking for a place where to host the image publicly, you can search in google “free public image hosting” and chose one of the recommended options. I’m personally already a user of Google Photos so that is what I would use.
