Ability to add boxart?

[Petie]

The image you suggested for Super Mario Odyssey is a prime example of why we haven't opened this ability up to the public actually. Banners in particular have some very specific requirements, the first of which is that the source image is at least 930px wide. You obviously had no way of knowing that but I feel like we'd spend more time cleaning up images than we would just adding them ourselves as time permits if we allowed users to add them directly.
