Primary images returned by various types are only populated with filename

[wagnerrp]

The Person, Studio, Movie, and Collection queries all return some form of image, but only provide the filename. There is no mechanism to query additional information for those images, so attempts to access those datapoints will result in an error. For images coming from movies and people, this information can be accessed through other queries available to the parent, so some method could be devices to properly populate those objects.
