When you hit the mouse on each guest (for example Marie-Agnes Gillot) a photo of that guest appears on the left side of the website. And with other guest the action would be the same.
I’m searching everywhere information about how to make changing images on static design, but unfortunately I can’t find out how it works…
The way I would do it would be creating a container and insert there all the images that you want to show, use position absolute and opacity to stack them all together and then affect the opacity and visibility with interaction hovering the names.
Maybe there’s a better way 
Works nice for now.
