Global to Adapt plugins: Placeholder image alt text

[kirsty-hames]

Subject of the issue

Do we need to include placeholder alt text in example.json files? I often find this doesn't get removed from courses unless it's being replaced.

              "_graphic": {
                  "src": "course/en/images/example.jpg",
                  "alt": "Placeholder graphic",
                  "attribution": "Copyright © 2019"
              }

When an alt attribute is left empty the image is ignored and I think this would be a more suitable default. It's more of a nuisance to include alt text when not needed never mind placeholder text. In most use cases, an image is decorative or content is already covered by the display text.

I would suggest a _comment attribute in the example.json or improve the description in the README (e.g. What alt text is and when to use it.)

Plus, we wouldn't need to include 'graphic' in image alt text so we're setting a bad example.

Yes - I agree, no we don't need default placeholder text...
