Link local file on Lovelace editor

Hi to all, I am in work to create my Lovelace screen.
I have made a plant of my house and I want to use in home assistant.
Now am trying to insert on Lovelace but I wrong the code.
I start by the example and change any variable, in the line of image a write
image: /home/pi/Documents/First image.png
But doesn’t work

Up please.
I put /local/directory but doesn’t work.
What I wrong?

Sorry but I don’t understand, I make a question about home assistant, if no one reply to me it’s not a problem for you, it’s only problem for me
