I am planning to make a universal app to support retina display. It will be a quiz with more than 100 questions. So, for the bg images the suffix will be: iPhone, iPod:320X480 = photo.png, retina iPhone, iPod: 640X960 = photo@2x.png iPad: 1024X748 = photo~ipad.png and for retina iPad 2048 X 1496 (apple doc?) (1536?) = photo@2x~ipad.png . Do I need to write any additional code? Would it be too much to include 4 images for every question, that means 4 images X 120 questions = 480 images!!!Would it be to heavy?

    The suffix the OS is looking for is “@2x.png“

    So if you want to do separate graphics for iPhone versus iPad, put those differences in their filenames before the @2x part.

    And yeah, four images does seem a bit like overkill. Why not just simply have regular resolution image and a high resolution image for various UI widgets used in both your iPad and iPhone versions?
