Plant-sensor entity Picture does not load?

Hi!

maybe someone can detect the reason, why the entity picture for one of my plant sensors does not load?
The sensor was added today … the other ones in summer this year …


    plant.calathea:
      friendly_name: Calathea
      entity_picture: /local/img/plants/calathea_.jpg

    plant.strahlenaralie:
      friendly_name: Strahlenaralie
      entity_picture: /local/img/plants/strahlenaralie.jpg

    plant.citrus:
      friendly_name: Zitrone
      entity_picture: /local/img/plants/citrus.jpg

The local/img/plants/citrus.jpg can’t be loaded

Here’s what the developer tools is showing:

And the image has been uploaded to the path:

I can also open it in Visual Studio Code - and it will be shown.
So… right now, I don’t really see where my issue lies… Neither I see any typo - or anything else…
