Supertile thing, HTML/image attribute?

Im making a weather tile that has HTML or image attributes from hubitat WeatherUndergorund driver. When I put that attribute into a super tile it shows up like this.

Same deal if I make Hero Tile with attribute

Looks like this on Hubitat device and works on Hubitat dashboard

Any way to make this work?
