This is done with 3rd party tool https://interactive-img.com.  It's a low cost tool, priced at $60 a year.
This was created using https://app.genial.ly They have an impressive free level if you don't mind the watermark in the lower left. I like this one because the memorials can pop up on hover vs click, which is a nice feature. It also has a nice array of on load, continuous or on hover animations which could make it a nice selling point.
