I have a list with an Image column and 3 descriptor fields. I want to create a custom display that has the image in section 1 and the 3 descriptors stacked in section 2. I can't figure out how to get the image to display.

   "elmType": "img",
   "style": {"width": "150px","height": "125px"},
   "attributes": {"src": "[$myImage]"}

The idea is to display the image associated with the list item. I've seen many examples where the src value is coded to a specific image. That's not the purpose here. Think product catalog. 

So - how do I get the image to display?
