[Support]: Snapshot Image API

[github-tijlxyz]

Describe the problem you are having

I had the problem that the home assistant notifications using the blueprint were not showing the cropped snapshots that I configured.
So I looked at the API, on home assistant https://[home assistant]/api/frigate/notifications/[event]/snapshot.jpg?crop=1 or directly from frigate http://[frigate]/api/events/[event]/snapshot.jpg?crop=1 it shows exactly the same as without ?crop=1. What am I doing wrong here?

Is the event over? You don't have crop enabled in the config so if the event is over it won't be adjusted

[github-tijlxyz]

ah ok that's the problem, is there any way to store the snapshot cropped and not cropped for later access?

[NickM-27]

Not both, one or the other
