Button using a photo and how to call a source?

Configuration
1

Hello.

Can I get a small button with a photo as the full button?

I want to set up a remote for SkyQ and want to add images like these as buttons to select specific channels.

The custom mini button seems to use MDI icons
I think the picture entity card is what I want but not entirely sure
There is a picture card too

As I want the button to call a source from the below code I am not sure an entity is what I want? I am also not entirely sure how to “call” a source using a button press

    host: 192.168.1.106

    generate_switches_for_channels: true
    sources: 
      SkyOne: '1,0,6'
      SkyNews: '5,0,1'
