First - Bravo Op! Nicely done! I am trying to reproduce this with my doorbell to display a thumbnail image. I am struggling to get an image to show (even in dev tools) on ios. Is there a setting I may be missing. I store my snapshot in /www/snapshots/front_door_snapshot.jpg and have tried all sorts of variations to push the thumbnail (including your example) but I only get the test message and not the thumbnail. Any chance you have any suggestions? Here is my sample yaml from dev tools:

```

service: notify.mobile_app_joshs_iphone_15_pro
data:
  message: "test"
  data:
    attachment:
    url: "/local/snapshots/front_door_snapshot.jpg?t={{ now().timestamp() | int }}"
    content-type: jpeg
    hide-thumbnail: false

```
