Your spotify comparison does not really match perfectly. Playing for yourself (license permitted) vs playing for the public (license not permitted) is keeping the same content source but changing the end user.

With the photo, you are a single user browsing the photo on either website A or website B. Website A “owns” the photo, and website B has embedded it, but in both cases you are getting the photo from website A.

Since you are the same user both times, and are getting the photo from the same place both times, at first glance I would regard this as not breaking any license terms since the two parties (image host, end user) are the same, but I can accept that this is a point of contention.
