May be I have missed something in your question. But why you need to reload the entire view? You are using an UIImageView to display your image, right? And you are not showing any kind of scroll, but only a next button, right? Then why don't you just set the image property of UIImageView when the button is tapped.

// in button handler
myImageView.image = [UIImage imageNamed:@"new_image.png"];

Perhaps you could use a paged UIScrollView with three uIImageViews and always have the previous, current and next image loaded. This way when the user hits next, it scrolls animated to the next image. When page 3 is loaded, it programmatically sets the second image view as the desired next image, sets the image you came from on the first image view, and sets the scroll view non-animated to page two and loads the next image in the third image view.

Sounds complicated but basically you are giving the appearance of an infinite scroller but only pulling one image at a time except for initial load of three.

You could try looking at the "PageControl" Example Project in the XCode Documentation. It should give you a good starting point.
