image size in adaptive card

Occasional Contributor

As per MSFT Chats Limitations, the maximum length of the message is approx 28Kb which includes text, images, links, etc.


But while working with the Adaptive Card that includes image and description text, we are able to load images with 250 Kb in size from azure storage through Image URL. Kindly let us know how the image of more than 250 KB can be loaded into the adaptive card since the max limit of an adaptive card is 25KB only.

You can use base64 to send the image, although the issue then is if the total size of the adaptive card is exceeds the size limit, haven’t been able to bypass that one yet.
