Hi there, the supersize option only works by resizing the height of the image to fill the window so you'll need to change the dimensions of the original image to make it more in perspective. You could zoom in and crop to the top half of the image so it's a landscape, rectangular shape, this way when it re-sizes it the sides of the image will reach the edge of the browser window.
The tile bg option is only available with a static bg, it doesn't work with the supersize option. If you wish to use this, turn off supersize prior to settings the tile options in the bg settings in the color control tab.Go to the full post
