Using steam sensor's entity_picture as the image for picture-entity

Hello,

Today is the first day i tried lovelace and it’s looking good, except i am stuck with this issue,
I am trying to show my steam sensors as picture-entity where i can see the profile picture, below it is the name and the status.
except it wont allow me to create the picture-entity without an image and using a template didn’t work (maybe that’s my fault cause i am not really that good in all of this.

this is what i tried using the template

image: “{{states.sensor.steam_11111111.attributes.entity_picture}}”

but that also didn’t work, thanks in advance
