Я не знаю зачем там нужны дополнительные скрипты, наверное для каких то эффектов. Вот что выходит у меня:

<div id="testFrame">
	<ul class="slidee">
        <li><img src="http://lorempixel.com/400/200/sports/1/" /></li> 
        <li><img src="http://lorempixel.com/400/200/sports/2/" /></li> 
        <li><img src="http://lorempixel.com/400/200/sports/3/" /></li> 
        <li><img src="http://lorempixel.com/400/200/sports/4/" /></li> 
        <li><img src="http://lorempixel.com/400/200/sports/5/" /></li> 
	</ul>
<div id="forw"> -> </div>
<div id="back"> <- </div>
</div>

<div id="show">show</div>

СSS:

#testFrame{
    width: 600px;
    display: none;
}
#testFrame ul li img {
    width: 200px;
    float: left;
}

var sly12 = new Sly('#testFrame', {
	horizontal: true, // Switch to horizontal mode.

	// Item based navigation

	// Classes
	draggedClass:  'dragged',  // Class for dragged elements (like SLIDEE or scrollbar handle).

     });
     
     $('#show').click(function(){
        $('#testFrame').css('display', 'block');
        sly12.init()
     });

Конечно настройки никакие, но я и не стал вдаваться. Но вроде работает на JQuery.js и Sly.js. Я не понимает зачем тебе его грузить слайдер аяксом?
