Placing an image in this repository will cause a banner to be displayed under the subsite title for every page of the site. Only the first image will be used, if multiple are available. The image should be at most 936px wide. If the image is smaller, it will be displayed centered in the banner area; if larger, it will be scaled to 936px wide. The image height is variable, but will only be displayed up to 250px tall. If the image is smaller, the banner area will conform; if larger, it will be cropped to 250px.
