Making textures looking good on Iphone and on Ipad.

Hi guys, I need to make a game that runs perfectly on Ipad, Iphone and Ipod touch. The game is in 2D, so I am using sprite manager 2 to manage most in game graphics.

Since Ipod and Ipad use two different ratio and resolution, what is the best way to handle the texture? For example, my game background is 1024x768 so it looks good on Ipad. But on the ipod touch, it gets scaled to 480x320, so things are a bit skewed.

Is there a simple way to have 2 JPG for each elements and use the good one?

Thanks!

If you’re planning to have two different resolutions, it might be a good idea to make them vector images, so when you do scale them down, the quality isn’t that skewed. I know Adobe Illustrator does vector art, but I don’t know if this will help that much.

If the art is already complete, then my suggestion is useless. Maybe another piece of software or Illustrator can convert the JPEG’s.
