Shifts to an image that follows the ImageSlider.CurrentImage.
The SlideNext method shifts to an image that follows the ImageSlider.CurrentImage via code. To get the next image, use the ImageSlider.NextImage property. An end-user can navigate to the next image using the 'Forward' button that is made visible on hovering the right middle area of the ImageSlider.
The SliderBase.SlidePrev method is the reverse of the SlideNext.
