This readme file will help you understand the banner's different sizes requirements.

All banners' filename that include @2x requires both 2X and 1X sizes. The 1X version design must be the same design as 2X:
-- 1150x320@2x - 1150x320
-- 1920x360@2x - 1920x360
-- 1920x120@2x - 1920x120
-- 1920x120v2@2x - 1920x120v2
-- 640x100@2x - 640x100
-- 940x390@2x - 940x390


Banners that DO NOT require 2x version:
-- 160x360
-- 1200x500
-- 1300x240
-- 1200x1200_PushNotification
-- 1080x1920
-- IG_1200x1200
-- SM_1200x628
-- 1200x1200
-- 1200x628
-- 728x90
-- 300x250


Banners requires a duplicated version (same size & design, different filename):
-- 759x300 (+ duplicated size naming convention 759x300v2)
