Dude thank you so much. From your suggestions I was able to get it to work in Android. What I did was remove the “entity_id” line you had, and replaced it with:
"image": "/api/camera_proxy/camera." & $split(topic,'/',3)[1] & "_alert"
And now the image appears as part of the notification! Now I am going to try to figure out a way to tap on it and have it load something that lets you pinch to zoom the image. The notification image isn’t pinch zoomable, nor is the camera card in the companion app.
