js问题：怎么把这段代码改成在6张图片中交替显示呢？

Question

setInterval('autoiFocus()',5000);
var atuokey = false;
function autoiFocus() {
if(!$('ifocus')) return false;
if(atuokey) return false;
var focusBtnList = $('ifocus_btn').getElementsByTagName('li');
var listLength = focusBtnList.length;
for(var i=0; i<listLength; i++) {
if (focusBtnList[i].className == 'current') var currentNum = i;
}
if (currentNum==0&&listLength!=1 ){
moveElement('ifocus_piclist',0,-225,5);
classNormal('ifocus_btn','ifocus_tx');
classCurrent('ifocus_btn','ifocus_tx',1);
}
if (currentNum==1&&listLength!=2 ){
moveElement('ifocus_piclist',0,-450,5);
classNormal('ifocus_btn','ifocus_tx');
classCurrent('ifocus_btn','ifocus_tx',2);
}
if (currentNum==2&&listLength!=3 ){

addLoadEvent(iFocusChange);

我才写了一个类似的 就是用了 透明度设置的
 
  <script language="JavaScript1.2">      var conid=1;
      var totalMes=14;
    function getposition(){
       
   
     var id='thisid'+conid;
    var urlpic='images/a'+conid;
    var thispos=document.getElementById(id);
    thispos.style.display='block'
    thispos.style.backgroundImage='url('+urlpic+'.jpg)';
    var xpos="";
    var ypos="";
   
    xpos= 100+Math.round(Math.random()*400);
    ypos= Math.round(Math.random()*20);
   
    thispos.style.pixelLeft=xpos;
    thispos.style.pixelTop=ypos;
    document.getElementById(id).style.zIndex=conid;
   
   
    showstep();
   
    }         
   
   
    function showstep(){
   
    if(document.getElementById('thisid'+conid).filters.alpha.opacity!=100){   
    document.getElementById('thisid'+conid).filters.alpha.opacity=document.getElementById('thisid'+conid).filters.alpha.opacity+5;
    setTimeout('showstep()',100);
    }else{
    showfade();
    }
     }
     function showfade(){
    
     if(document.getElementById('thisid'+conid).filters.alpha.opacity!=0){   
    document.getElementById('thisid'+conid).filters.alpha.opacity=document.getElementById('thisid'+conid).filters.alpha.opacity-5;
    setTimeout('showfade()',100);
    
     }else{
     conid++;
    if(conid==(totalMes+1)){
conid=1; 
    }
    getposition();
    
     }
    } <div class="pic1" id="thisid1" style="filter:alpha(opacity=0)" style="display:'none'"></div>

html只给了一个 你要几个改一下就可以了
