We need a frontend, which I would prefer to be made in Angular, React, or Knockoutjs.
We need access network with load balancing capabilities, for high availability.
I would personally make use of cloud computing instead of using my own premises network. I can make use of features provided by the cloud.
For storing images I would use services like S3 from AWS, or similar home-backed one.
For event e.g. LIKE, LOVE, etc I would use streaming (event processing) and messaging. I would need a distributed architecture because users can access images from anywhere, and latency is important in a timeline scroll on the app.

These sort of questions are open-ended so you can just use your wild imagination. Interviewers are normally checking your thinking abilities in terms of architecture and scalability.

The application and service FACEY.TOP represents briefly how Instagram works.

But this is not a question for the interview. Or, probably, if the person has the imagination at least how to start and what is expected as a final implementation.
