Mentre c'ero ho corretto anche il codice per inserire più slide... fatti una copia del tuo, si sa mai, e inserisci questo al posto di quello che hai, poi aggiungi le tre immagini 4, 5, 6:
<div id="wrapper-center">
<div id="slide">
<div class="joomscontmask1">
<div id="joomscontbox1">
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide1.jpg" alt="img1" />
</div>
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide2.jpg" alt="img2" />
</div>
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide3.jpg" alt="img3" />
</div>
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide4.jpg" alt="img4" />
</div>
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide5.jpg" alt="img5" />
</div>
<div class="inner">
<img src="templates/<?php echo $this->template ?>/images/slide6.jpg" alt="img6" />
</div>
</div>
</div>
<div id="prev1" class="prev1">
</div>
<div id="next1" class="next1">
</div>
</div>
</div>
<script type="text/javascript">
window.addEvent('domready',function(){
var hs1 = new noobSlide({
box: $('joomscontbox1'),
items:[1,2,3,4,5,6],
size: 940,
autoPlay: true,
interval: 3000,
fxOptions: {
duration: 500,
transition: Fx.Transitions.Sine.easeOut,
wait: false
},
buttons: {

});
</script>
