Like an Image Slide Show? As in an image is shown then after an amount of seconds it changes to another image.... the cycle repeats
If so then, right-click > Add > Image Slide Show
Then add in the milliseconds for it to switch between images and at the bottom add all the images it will cycle through in the slide show.
You can also add blank images to fake nothing shown between images
Not certain if you can do that with different scenes, as in scene transitions by x-amount of time automatically by it self
