Using random photos in Storyline 2

I wanted to use the random photos from as wallpaper similar to Aman's drag and drop exercise in his LinkedIn post below. Does anyone know how this was done? I am creating a trigger and using the URL but it opens up a separate browser window. I'm sure it's got to be something simply I'm doing wrong.  (

In fact using Unsplash for random images is quite easy.

Refresh the page and you notice its a random image every time.

Basically its just a WebObject that loads a random image into itself at start.
