In the Add panel on the left side of the editor, you will find the Slideshow element and more that you can add to your canvas.
A great way to show a series of pictures without losing too much canvas space is a slideshow. This element works best if all images are the same size. There are some settings in the objects tab to change the style of the slideshow: you can toggle on or off the arrows and dots, choose different transitions and choose to play the slideshow automatically. You can also control the slideshow with every element on your canvas by linking it to that element.
