Phone app: How do I get it to notify me when new images are added?

I see it puts a red box when one is removed and green when added? But I don’t see anyway to add images to the conditions if trigger?

changes to images can be monitored by monitoring changes to img elements’ src attribute or property. check out https://distill.io/docs/web-monitor/what-is-visual-selector/#how-to-monitor-changes-in-the-image
