==Background
Page Previews will be allowed to display free and non-free images whereas the PageImages API //should// only be returned free images by default – even though this isn't the case at the moment, we should assume that it's going to be when we start to roll out Page Previews.
Using the new API (see {T123445}), Page Previews will request images which are non-free as well as free images.
==Story
As a user who is viewing a preview for any Star Wars related content, I want to see an image that is relevant to the content I am viewing rather than an unrelated photo of something like one of the filming locations so that I can understand more about the topic quicker
== Acceptance Criteria
- The RESTBase API can return both free and non-free images on a per-wiki basis
- The above is only valid behavior in the context of Page Previews (web and iOS/Android apps) but not, for example, Related Pages
- Notify apps teams on changes to RESTBase
