<h3>Examples</h3>
<p><a target="_blank" href="showasp.asp@filename=demo_htmlimage2">HTMLSelect</a><br />
In this example we declare an HtmlImage and an HTMLSelect control in an .aspx
file (remember to embed the controls inside an HtmlForm control). Then we modify
the src property of the HtmlImage control based on user choices. The value
selected in the HtmlSelect control determines which image to display.<br />
