Schema Markup using URLs for article images fail validation.

[andreban]

On the Article specification, the documentation says that the image field can be "Repeated field of ImageObject or URL".

AMPBench validation for the field currently fails if an URL is used, of if a sequence of objects is used. The validation seems to only accept ImageObjects (as per this code section).

The example below, extracted from the docs fails:

{
  "@context": "http://schema.org",
  "@type": "NewsArticle",
  "image": [
    "https://example.com/photos/1x1/photo.jpg",
    "https://example.com/photos/4x3/photo.jpg",
    "https://example.com/photos/16x9/photo.jpg"
  ]
}
