HtmlInputImage Class
Assembly: System.Web (in system.web.dll)
Use the HtmlInputImage control to create a button that displays an image. You can programmatically control the action associated with the HtmlInputImage control by providing an event handler for the ServerClick event.
The coordinates where the user clicks an HtmlInputImage control can be determined by using the ImageClickEventArgs.X and ImageClickEventArgs.Y properties of the System.Web.UI.ImageClickEventArgs object that is passed as a parameter to the user-defined event handler.
For a list of initial property values for an instance of HtmlInputImage, see the HtmlInputImage constructor.
The following code example demonstrates how to use the HtmlInputImage control to create a button that displays an image.
