Is your feature request related to a problem? Please describe.
We obtain urls of images from a cdn, however, we sometimes do not know if these images are valid or working urls.
When creating the adaptive card object, we would set these urls unknowingly and they would fail on the front end. I am hoping that a feature can be added to add a fallback capability for these failing images.
Describe the solution you'd like
I am hoping to have it set up so an image element, when its url fails to resolve, resorts to the next image element in the fallback field.
