Just to add some additional context to this, you will probably get the same result from any action that attempts to embed an image from SharePoint in Teams. I've tried 3 ways from Sunday, and it just won't work. My suspicion is the desktop client doesn't know how to interact with SharePoint to retrieve the content in question. I'd **love** to have this fixed ASAP.

PS: I've also asked Copilot, the answers there were no better. 🙂

Zollinger , jordanmatas 

We got update from engineering team that, this is by design - image requests are not sent with any auth token, which is why we request that all cards images be publicly available. 
As an alternative, you can convert the image to base64, or upload it to a publicly accessible image repository. 
 
 
 

Thanks, 

Prasad Das

    I think the problem is a different one and still exists. See https://techcommunity.microsoft.com/discussions/teamsdeveloper/images-in-adaptive-cards-in-new-teams-client-not-showing/3977146/replies/4025543. I have tested the exact code for the adaptive card with https://adaptivecards.io/designer/ and it shows the image correctly. Could you please tell us when the product team considers to fix this? Its been an issue since the new Teams, it was acknowledged, and even fixed in a previous version. This is very frustrating.

    Hi Prasad,
    Would it be possible to update Adaptive Cards documentation and include this information?
    Today it is recommended to use image from SharePoint: https://learn.microsoft.com/en-us/power-automate/image-share-sample

    There is no official info on the base64 encoding method - the only workaround for business users who can't put image to the open url,

    You should also mention the payload size limit, what makes image handling more tricky - you need to resize it to keep the payload small and there is no MS tool to resize and encode image.

    BR,
    Piotr
