// create a new project

// double click the main.nib to open interface builder

// drag the HIImageView to your window and size it.

// in the ImageViewInspector/Control set the

// id = 130

// save & quit interface builder

// place your background image in your project folder

// drag the image to the resources folder of your xCode project

// this uses QuickTime so you need to add the QuickTime.framework to your project.
