Cover Image API
The Summon Cover Image Resolver is a URL resolver that takes a well known URL format and returns the best cover image based on per-client preferences and subscriptions. The cover image URLs are meant to be used in standard HTML <img> tags, and the resolver uses standard redirects and content types to allow browsers to retrieve the images directly. The Cover Image Resolver is not an authenticated service, but the services that a client subscribes to will determine the images that client can access. The response format may be either image/gif, image/jpeg or image/png. The Cover Image Resolver does not produce images itself, but it aggregates images from several different image providers depending on user preferences and subscriptions. The quality, size, and format of images returned may vary depending on the services to which a particular client subscribes.
