	<!-- Configure a few settings -->
	<script language="JavaScript">
		webcam.set_api_url( 'test.php' );
		webcam.set_quality( 90 ); // JPEG quality (1 - 100)
		webcam.set_shutter_sound( true ); // play shutter click sound
	</script>
	
	<!-- Next, write the movie to the page at 320x240, but request the final image at 640x480 -->
	<script language="JavaScript">
		document.write( webcam.get_html(320, 240, 640, 480) );

		&nbsp;&nbsp;
		<input type=button value="Take Snapshot" onClick="take_snapshot()">
	</form>
	
	<!-- Code to handle the server response (see test.php) -->
	<script language="JavaScript">
