This helps you set a custom background in your new tab page

Simply drag and drop the image you want as your wallpaper, and voila, it is the wallpaper on your new tab page. Or, choose 'Set Background' from the settings button from the bottom left, and get a mini editor to rotate or resize your image. You can even add your name using the same settings button.
