An object that represents the source of images that can be displayed within tooltips.
Use the ToolTipControllerShowEventArgs.ImageIndex property to specify the image to be displayed in the current tooltip. This property addresses the image by its index in the image list referred to by the ImageList property.
Initially the ImageList property stores the value of the ToolTipController.ImageList property provided by the ToolTipController that fires the current ToolTipController.BeforeShow event. You can assign another image list to the ImageList property if required.
