[Plugin: Shadowbox JS] change output of shdowbo.js on pages (footer

I am trying to find the file where I can change the parameters that appear in the footer of the page with this plugin:

this:

<!-- Begin Shadowbox JS -->
<script type="text/javascript">
	var shadowbox_conf = {
		adapter: "base",
		language: "en",
		players: ["img"],
		animate: true,
		animateFade: true,
		animSequence: "sync",
		autoDimensions: false,
		modal: false,
		showOverlay: true,
		overlayColor: "#000",
		overlayOpacity: 0.8,
		flashBgColor: "#000000",
		autoplayMovies: true,
		showMovieControls: true,
		slideshowDelay: 0,
		resizeDuration: 0.35,
		fadeDuration: 0.35,
		displayNav: true,
		continuous: false,
		displayCounter: true,
		counterType: "default",
		counterLimit: 10,
		viewportPadding: 20,
		handleOversize: "resize",
		handleUnsupported: "link",
		initialHeight: 160,
		initialWidth: 320,
		enableKeys: true,
		skipSetup: false,
		flashParams: {bgcolor:"#000000", allowFullScreen:true},
		flashVars: {},
		flashVersion: "9.0.0",
		useSizzle: false
	};
	Shadowbox.init(shadowbox_conf);
</script>
<!-- End Shadowbox JS -->

I want to change the overlay color from black to white and, more importantly, the “handleOversize” to “none”.. I can’t figure out where/how to change the generated code in the plugin files.

I’ve tried changing the values in the “shadowbox-js/inc/frontend.php” and “shadowbox-js/inc/admin.php” (the only places I can find this same code) but it does not change the output on the page.

Thank you
