iOS Changing image of a view

[Nraygun]

I loaded a number of images into an array in a ViewDidLoad method:
myImagesArray = [NSArray arrayWithObjects: [UIImage imageNamed"image1.jpg"], [UIImage imageNamed"image2.jpg"], etc., nil];

If I set the image of my view in this same method with this:
myImageView.image = [myImagesArray objectAtIndex:1];

it works.

If I do this last statement elsewhere in the same object I get a crash:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)'

If it works in one area(inside of ViewDidLoad) why doesn't it work in another area? I thought the scope of variables was across all methods in a class.

What am I doing wrong?

Is the array retained in any way? Arrays created by any method other than alloc/new/copy/mutable copy are all autoreleased and without retaining them they are prone to vanishing at any time.

That's probably it.

So I just need to throw one of these in, right?

[myImagesArray retain];
