Separate Photos on each slide

I am creating a slideshow with approximately 50 images. In the past, I've added multiple images using the image gallery on a single slide. Now I'm working on a presentation where it would be better to have a separate slide for each image. I know how to add images individually to each slide, but this would be time-consuming with so many images. Is there any way to add a group of images and have Keynote automatically place each image on a separate slide?

Thanks.
