Inserting huge images

Hi

I want to draw a really long level in photoshop. Say 60-70k pixels wide. Can I just to that, or are there better ways of doing this, memory wise?

I’m making a physical object that the character walks on, do I need to split the images, or can I just use a really big one?

Thanks!

A 70K pixels image will crash your app. 

I think you should chop them in smaller images.

For iPhone 3 or lowers, the maxed sized image should be 1024x1024,  for newer iPhone, they can handle 2048x2048.
