Use the property to place a graphic image onto a control.
Images with translucent or transparent colors are not supported by Windows Forms controls as background images.
This property is not supported on child controls whose RightToLeftLayout property is true.
When overriding the property in a derived class, use the base class's property to extend the base implementation. Otherwise, you must provide all the implementation. You are not required to override both the get and set accessors of the property; you can override only one if needed.
The following code example adds a Button to a form and sets some of its common properties. The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. Next it sets the and resizes the button to the same size as the Image. The example then sets the TabStop to true and sets the TabIndex property. Lastly, it adds an event handler to handle the Click event of the button. This example requires that you have an ImageList named imageList1.
