Productivity tool for Google Slides™ and Google Photos™
Use this add-on to synchronise a Google Photos™ folder with Google Slides™.

The add-on is limited to synchronising 100 photos per hour.  If you have a large photo album, it may take some time to fully sync.

Due to this add-on's recent popularity, it has been reaching Google's limit for accessing Google Photos which has in turn caused errors for most users.  To try to limit traffic, if the presentation hasn't been accessed in the last 7 days, photos will only be synced once per day.  To allow the photo sync to continue working correctly, please open the Slides presentation at least once a week.  I'm sorry for the inconvenience and we are working to find a better more permanent solution that works for everyone.
