Usa of map image of AutoMover path as additional layer on house garden map

[alberpao]

Hello, I'm using HA with picture of the house including garden to show in a glance full status like lights (internal, external, garden) and other like smart plug status or EV car battery charge etc.
Now I have the Automover (430X Nera) and using correctly an image map of garden to show current position and path: now the idea is to integrate this "automover" path map into the house and garden one: I was using a transparent picture with geo reference for corners into Husqvarna integration with the idea to use it as "overlay" into the house and garden overall status but I still struggling to make it visualizing into a different panel than Husqvarna one.
I had added those following lines to try to add it as overlay on the bottom of the other pictures for house and garden:

     - type: picture
            style:
              top: 0%
              left: 0%
       image_entity: image.am430x_nera_map

But it do not work (it generate an error "Unknown type encountener picture" followed by the code above).

Please note I'm not so much familiar with code YAML so forgive me if I do elementary errors! e.g. not sure if top/left positioning meaning something for this...

Any idea how to add this "path"overlay and icon into a different panel than "Husqvarna" separate one that I create using all items that work there perfect?
