title: Choosing image size for react native app
body: <p>I need some fullscreen images for a react native app. What size should I stick to? Should I add multiple images for different resolutions, like one of width 320, one of width 480, 720, 920, 1280, 1920 etc and choose them according to <code>Dimensions.get</code> output? If so, which sizes should I include? Or maybe I don't need that much images and sticking to one with average resolution is still fine? What are best practices to choose image size?</p>
