Received the task to prepare the content for the next application of live Wallpapers for iPhones (which the screen saver come to life when you long tap).
Competitors strange dimensions: 854х1590, 1158х2000, 1500х2592.
They are not proportional to any of the iPhones. Among the guides do not find the desired information.
Can anyone tell me where these permissions, or where to look really to the required size.
