Change image settings here. Mode affects how images are stacked (pyramid = center image on top, horizontal = rightmost image on top) and whether the images are blended. Blend Margin determines how much of an image is transparent—10% would make the left and right tenths of an image transparent. Visible area determines how much of Sunset is visible at once. Larger values will squish images together in order to show more of Sunset simultaneously, smaller values will show fewer images more spaced out.
