Lovelace - fixed path for images?

Configuration Frontend
1

Trying to organize my images for Lovelace, I setup

  - type: picture-glance
    title: Control room
    entities:
      - light.bureau_left
      - light.bureau_right
      - light.office_inside
      - light.office_outside
      - switch.sw_kantoor_template
      - sensor.control_room_motion_sensor
      - sensor.control_room_motion_sensor_light_level
      - sensor.control_room_motion_sensor_lux
      - sensor.control_room_motion_sensor_temperature
    image: /config/lovelace/images/control_room.png

which returns the broken image icon, the entities seem to load alright.
changing the location of the image and path to

    image: /local/lovelace/images/control_room.png

makes the image appear.

Is the path fixed to www (/local) ? If so, does this apply to other entities as well?
