A suitable image to use as the header banner in the entry for the anime. As with cover images, this should be official artwork or assets only. The image should be of decent quality and not too gaudy, it is up to yourself what you think would look good as a banner.
The image should ideally be cropped to 1900x400px and either .jpg (.jpeg) or .png format. However .png banners will be converted to .jpg (.jpeg) for storage.
