How to show landscape pictures on portrait screen?

Question

Images

Hello, here are the ways that I know:

1. in width - this is what most people do, but on a 9:21 ultra phone it is difficult to see the image
   
2. in height - a barbaric decision, cropping the picture is not cool at all
   
3. image rotation - I use this. When you click on the image, the background is darkened, it is centered. If the height of the photo is 3 times the height of the screen, it is tilted 90°. There is a button next to it to turn back. For me, as a developer, this is convenient. example(try from vertical screen)
   

Maybe you know some other ways?
