You can embed a slideshow directly into a Lucidpress document. The document can be played within a published document. Please note that it will not play within an email, PDF, or image.
Add a slideshow by first adding an image and then add a more images via the slideshow formatting in the right context pane by clicking the plus icon. You can then adjust the delay between each slide. Make sure to toggle "autoplay" if you would like the video to automatically play.
