OH3 - Image Receiver - not showing FTP-Images

Add-ons Bindings
1

I try to setup in OH3 a Camera Overview where the one with the last event pops in the middle of the Overview with a big Picture.

  1. If i setup the FTP-Upload Binding,
  2. configure the Image Receiver,
  3. import in the Frontend the openHAB Item “Image” Widget and
  4. add the “ImageReceiver_Item” in there, the result is:
    2021-05-08 10_33_56-HABPanel
    2021-05-08 10_33_56-HABPanel1006×673 80.1 KB

    In the Backend “ServerIP:PORT/#!/settings/items/ImageReceiver_Image” - There, the last FTP-image are working and also refreshing!

The Binding also works in the frontend, if i manually copy a Picture with a FTP Client to the openHAB FTP-Uploadfolder till a new event overwrites the latest image.

differences
Backend Image Properties:
data:application/octet-stream;base64,/9j/2w

Frontend Image Properties:
unsafe:data:application/octet-stream;base64,/9j/2w

Does anyone know how to fix this in the frontend, or is it maybe since 2019 keep staying a bug?
