Jquery slideder effects

Question

I'm trying to add Fade-In Fade-out effects to the homepage of this page but it doesn't seem to take effect, it rather stops working. I'd like only the fade effect.

The function code is as shown below

script>
        $(function(){
            $('#slides').slides({
                fadeOut: true,
                preload: true,
                preloadImage: 'img/loading.gif',
                play: 5000,
                pause: 4000,
                hoverPause: true,
            });
        });
    </script>

and the HTML is below

<div id="slides">
        <div class="slides_container">
                    <a href="#" target="" ><img src="images/wire2.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title="" ><img src="images/wire1.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title="" ><img src="images/wire3.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title="" ><img src="images/wire4.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title="" ><img src="images/wire5.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title=""><img src="images/wire6.jpg"width="570" height="270" alt="Slide 1"></a>
                    <a href="#" title=""><img src="images/wire7.jpg"width="570" height="270" alt="Slide 1"></a>
         </div>
      </div>

These are the options slide has:

preload: !1,  
preloadImage: "/img/loading.gif",  
container: "slides_container",  
generateNextPrev: !1,  
next: "next",  
prev: "prev",  
pagination: !0,  
generatePagination: !0,  
prependPagination: !1,  
paginationClass: "pagination",  
currentClass: "current",  
fadeSpeed: 350,  
fadeEasing: "",  
slideSpeed: 350,  
slideEasing: "",  
start: 1,  
effect: "slide",  
crossfade: !1,  
randomize: !1,  
play: 0,  
pause: 0,  
hoverPause: !1,  
autoHeight: !1,  
autoHeightSpeed: 350,  
bigTarget: !1,  
animationStart: function () {},  
animationComplete: function () {},  
slidesLoaded: function () {}  

I don't think slide by it self has fade in and out effect.
