As a user I want to get a quick overview of what an item is about. The header should give me this quick intro.
To make it easier to recognize what an item is about (and make it easier to spot mistakes in image data) we will show an image for an entity in the header.
We need to solve:
- Which image to show? Go the same way as Special:Nearby and ArticlePlaceholder!
- What to do with landscape vs portrait pictures?
- What to do on property pages? Do they have images? They might have the logo of an institution.
- What to do with entities that don't have an image?
- How much hints do we want to give to how to change it?
- Licensing requirements? We need to link to Commons?
