Hi guys, I am re-styling the family site because the angency that previously have done the site do a poor work. I am working on java to have good graphic results. here it is my code:

<script type="text/javascript">
google.load("mootools", "1");

var scroller = null;
var position = 0;

function scrolla(movement) {
position += movement;
scroller.scrollTo(250 * position, 0);

return true;
}

google.setOnLoadCallback(function() {
scroller = new Fx.Scroll('container');
});
</script>

here it is the example:

If I want to preload mootools.js in the head what I have to change in the code?

How can I set a autonomous rotation?
How can I set "stoppers" at the end of the pictures?

the finished gallery will be released open source code.
Sorry for my noobness
