Lovelace custom:button-card - change image on state change

Configuration Frontend
1

Hello all. New to HA but really like it and I have the Custom:button-card working. It is very nice and exactly what I want to use.

I am creating custom images to use as icons. My question is how would I change the image when I click the button. Light bulb on when lights are on and Light bulb off when lights are off.

Thank you for any input or help. This is really nice work from the developers.

here is a simple example on how I do it, note that you have to set show_entity_picture to true

        entity: binary_sensor.dome_dining_room_window_1_sensor
        name: Comedor
        show_entity_picture: true
        tap_action:
          action: more-info
        state:
          - entity_picture: /local/pics/window-closed.svg
            value: 'off'
            styles:
              card:
                - width: 190px
                - border-radius: 13px
          - entity_picture: /local/pics/window-open.svg
            value: 'on'
            styles:
              card:
                - width: 190px
                - border-radius: 13px

Thank you so much. This worked out great and I now have the text change color as well. It all makes sense now.

I really appreciate your help,

Here is the code I finally came up with.

cards:
      - type: 'custom:button-card'
        entity: light.office
        name: Office Lights
        show_entity_picture: true
        show_state: true
        tap_action:
          action: toggle
        state:
          - entity_picture: /local/icons/hueLigtOffSmall.png
            value: 'off'
            styles:
              card:
                - width: 160px
                - border-radius: 14px
                - padding-top: 10px
                - padding-bottom: 10px
                - margin-bottom: 20px
              name:
                - font-size: 18px
                - color: gray
                - align-self: middle
                - padding-bottom: 10px
                - padding-top: 20px
          - entity_picture: /local/icons/hueLigtOnSmall.png
            value: 'on'
            styles:
              card:
                - width: 160px
                - border-radius: 14px
                - padding-top: 10px
                - padding-bottom: 10px
                - margin-bottom: 20px
              name:
                - font-size: 18px
                - color: yellow
                - align-self: middle
                - padding-top: 20px
                - padding-bottom: 10px
