Use the Image control to display an image on the Web Forms page. Setting the ImageUrl property specifies the path to the displayed image. You can specify the text to display in place of the image when the image is not available by setting the AlternateText property. The ImageAlign property specifies the alignment of the image in relation to other elements on the Web Forms page.
This control only displays an image. If you want the image to behave like a button or need to determine the coordinates where the mouse pointer is clicked on the image, use the ImageButton control.
