When I do a Google Image search, and click the thumbnail which shows me the Google image card, and I click the "visit" link I expect to be taken to a page with the image on it.

With Pinterest results this sometimes happens: https://imgur.com/a/ktyNG

But not always: https://imgur.com/a/RrjJG

Notice how in the second link Pinterest is asking me to log in, even though I am clearly already logged in.
