Adding various aspect ratio images to a Keynote presentation
I'm trying to put my first presentation together using Keynote (v13.2) macOS Ventura 13.4.1(c) containing bullet-point slides and lots of photographic images of various aspect ratios - 4x3, landscape and portrait, square and non regular sizes. I'd hoped to be able to simply add the images with a black background when not precisely 4x3. The portrait orientation crops to landscape and the format tabs don't seem consistent and are confusing to put it mildly. Any help gratefully received.
