OH3: Item Image Type - How to specify a URL?

I answered on the original post.
Basically you have to pursue one of the following options:

  1. “URL-item”: the item just stores a URL to an image. then the item is of type string and you should use a corresponding widget (e.g. oh-webframe-card)
  2. “Image-item”: the item stores an image. then the item is of type image and the corresponding widget is oh-image-card)
