If you want a series of Images to cross fade into each other and then the whole cycle loop you will know this is impossible in PowerPoint. We like impossible.
This AddIn for Windows versions of Office from 2016 and later cretaes new animations that will do this.
Simple to use just align the pics over each other, select them all and click one button.
To Insttall just run the installer with PowerPoint closed. There will be a new Tab when you open with very simple controls.
