Size of UIScrollView and Size of Images

I have created this scrollview that loads the images dynamically. However I cannot get the images to cover the screen (should adapt to iPhone/iPad) one and one. And the height of the images is also corrupt (see attached image)

What am I doing wrong?

Image

Source to load images:

 for (int i=0; i < numberOfImages; i++) {

        // create image
        NSString *imageName = [NSString stringWithFormat: imageArray[i], i+1];
        UIImage *image = [UIImage imageNamed:imageName];
        UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

        // put image on correct position
        CGRect rect = imageView.frame;
        rect.origin.x = currentX + self.scrollView.frame.size.width/2;
        imageView.frame = rect;

        // update currentX
        currentX += imageView.frame.size.width + self.scrollView.frame.size.width;

        [self.scrollView addSubview:imageView];
        [imageView release];
    }

    self.scrollView.contentSize = CGSizeMake(currentX, self.view.frame.size.height);

    self.scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
    [self.view addSubview:scrollView];
    [self.scrollView release];
