The documentation (https://developers.google.com/freebase/v1/topic-response#references-to-image-objects) says it is https://usercontent.googleapis.com/freebase/v1/image/...
However, the freebase.com
web site creates links to images using the following URL:
https://www.googleapis.com/freebase/v1/image/...
(one is usercontent.googleapis.com
while the other is www.googleapis.com
)
Which is it?
