I built my app with SD images, how can I support HD?

What would be the best advice if I have my app built with SD images but I want it to look decent on iphone devices that support HD?

I've heard that simply doubling the size of all my images to get HD versions using Photoshop doesn't look good?

If I just don't support HD at all (turn retina display off in cocos2d) will it look blurred?

There are two types of source images: the raw graphics files you used to create your images, such as a Photoshop or Illustrator file, and then the actual images you exported from those programs to include in your app.

For example, you might take a 10 megapixel photo with a digital camera, but you size it down to include it in your app.

You do not want to increase the size/resolution of the pictures you exported for the app, because they do not have the graphic information to fill a higher image. It's like take a cup of water and expecting it to fill a bucket. The information is simply not there and it will look bad.

However, if you go back to your original graphics files, such as the 10 megapixel image in my example, you can create a new set of exported graphics for the higher resolution. You always start with your raw source files and then go down from there. Never start with files already exported for a certain resolution and then try to go up from there, or you will have pixelated poor graphics as the result.
