a html with a form is supplied to change some parameters with the mouse ..

<LI>Tips:
	<UL>
	<LI>Don't use <code>refresh=0</code> if you are not the only one, who
		want to access the video, cause this will lock the v4l device.
	<LI>Set <code>refresh=-1</code> if the image is NOT embedded in a 
		<a href=http://www.w3.org/MarkUp/>HTML</a>-page
		(or set it at compile time as the default or at runtime
		in the configuration file).
	<LI>Use w3cam.css to change the layout (don't forget to install and
		define the URL in the config file..)
