<b>An example with a basic event handler.</b> Here we've tied
several form values together with a simple event handler invocation.
The result is that the form values are updated in real-time as
the selection is changed using Jcrop's <em>onChange</em> handler.
</p>
<p>
That's how easily Jcrop can be integrated into a traditional web form!
