Capture dynamic link error from image viewer

Hi All,

Anyone figured out a way to do a condition on the image viewer where if the dynamic link returns an error then change to another source?

For example:
This link is invalid. nothing will display.

then a condition:


But what is that condition to make this work?

This post describing some recent changes to API error handling addresses that exact scenario.

In short, define an API request that fetches the image and conditionally display an alternate if an error is returned.
