SONOS card configuration

Hello!

I am struggeling with configuring the player in SONOS card.
What do I have to configure to show the radio station icon in the player and some radio station info?

This is the code that leads to the player’s look:

type: custom:button-card
entity: media_player.bad
name: RTL 102.5
show_name: true
show_entity_picture: true
entity_picture: /local/radio/RTL_102.5.png
tap_action:
  action: call-service
  service: media_player.play_media
  target:
    entity_id: media_player.bad
  data:
    media_content_id: media-source://radio_browser/675bd925-8b13-43fe-a1b9-43bb0f90fbbd
    media_content_type: music
    enqueue: replace

Use
entity_picture: http:/local/rRTL_102.5.png

I used:
entity_picture: http:/local/rtl5.jpg

If I use the SONOS favourite it shows it correctly;

But if I use the code above it shows this:

entity_picture: http://192.168.10.6:8123/local/rtl102.5.jpg

Above works for me

Yes it works for the favourite button.
But when it plays it does not show the icon.
