Use thumbnail from synology SS webhook in notification

Hello,

I was able to get the notification for motion working on my android but I am not able to find if its possible to use the thumbnail that comes in the jquery from the synology webhook rather than saving a snapshot locally on the HA server. The link in the webhook is publicly available and the image meets the requirements from what I can tell. If HA requires a local image be used, would it be possible to have HA download that thumbnail from the link?

Along with that, it seems we would have to create a way to clean out all of these thumbnails when they are saved locally. Is that correct?

Here is my automation:

alias: Synology SS Notifications
description: Rich notifications from Synology SS motion detection
triggers:
  - trigger: webhook
    allowed_methods:
      - POST
      - PUT
    local_only: true
    webhook_id: "REDACTED"
    id: Synology SS Notifications
conditions: []
actions:
  - action: notify.mobile_app_{my_phone}
    metadata: {}
    data:
      title: "{{trigger.json.title}}"
      message: "{{trigger.json.desc}}"
      data:
        image: "{{trigger.json.event}}"
mode: single

Thanks!

I was able to successfully use the downloader integration to download the file first based off the url in the webhook. This works for now i suppose but if there is a better way I would love to hear some suggestions.
