Launch image specifications
For your splash screen (launch image) you will upload a 2208x2208 PNG where the logo or other important artwork is placed within the center 1000x1000 pixels or so. We'll be cropping this image into the many different resolutions required for each different device and orientation, so we need your logo or artwork to be at the center, where no cropping will occur.
