The RenderAttributes method overrides the base class's RenderAttributes method to write the src attribute of the rendered HtmlImage control.

The RenderAttributes method is used primarily by control developers extending the functionality of the HtmlImage control.

The following code example demonstrates how to override the RenderAttributes method in a custom server control so that specific alternative text, accessible as a ToolTip, is always displayed with the HtmlImage control.
