You want to save it your applications Documents or Library folder. See the Files and Networking Programming Guide and specifically something like:

"Listing 6-1 Getting a file-system path to the application’s Documents/ directory:"

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Have a look at this snippet http://snipplr.com/view/28080/save-image-example/, each application has a 'Documents' folder where you could save the image too.

You would save it to the applications document or library folder. If you want the user to have access to it on the iPad, put it in the documents folder. If only code will access it, put it in the library folder.
