[Plugin: NextGEN Gallery] Replacing the Flash slideshow with jQuery Cycle Lite

I’m trying to implement jQuery Cycle Lite (https://www.malsup.com/jquery/cycle/lite/) instead of the Flash viewer. To get it to work, all it needs is a series of image tags like this :

<img src="images/beach1.jpg" width="200" height="200" />
<img src="images/beach2.jpg" width="200" height="200" />

So to get that I’m modifying the image browser function in nggfunctions.php, and I’ll call it like this: <?php echo nggShowImageBrowser(7); ?>. But that call will only output one image since the function expects an array, not just the gallery ID. So how can I use the echo syntax (instead of the shortcode) but return an array?
