How to search images on Google using Goggle Custom Search?

How to search images on Google site using Goggle Custom Search? I read that their Image Search API is now deprecated. And there aren't any examples with GCS.

For example I want to search images "play station 4" and add filter: show only large images.

How to do it?

I want to make a small PC application on C++/Qt and do http requests to extract images from reply.
