JS自动切换图片代码问题
js代码如下，里面有详细解释：
/**
1. 图片自动切换(更改img标签src属性)
a.制作一个切换函数
b.加载事件，完成间歇函数功能
2. 完成图片停止功能
3. 如果鼠标移出图片，则间隙函数要调动起来
4. 图片切换的时候对应的序号需要高亮显示
5. 当鼠标"移入"一个序号，则图片要显示对应序号的图片
当前序号也需要被高亮显示
序号有鼠标移入事件
6. 鼠标从序号移出要继续图片切换
*/
//图片切换功能
var i = 1;
function pic_change(){
//图片如果到达最后一个张，则计数器清空、归位
i++;
if(i == 8){
i = 1;
}
//全部序号"暗"下来
var lis = document.getElementsByTagName('li');
for(var j = 0; j < lis.length; j++){
lis[j].style.background = "green";
}
//当前序号背景色高亮显示
document.getElementById('xu' + i).style.background = "yellow";
var pic_obj = document.getElementById('pic');
pic_obj.src = i + ".jpg";
}
//加载事件函数，完成页面每次加载间歇函数的制作
var timer = "";
function jia(){
clearInterval(timer);
timer = setInterval('pic_change()', 1000);
}
//停止图片切换
function stop_pic(){
clearInterval(timer);
}
//鼠标移入序号发生变化的函数
//1显示当前序号对应图片
//2当前序号高亮
//3鼠标移出图片要继续切换
function xu_change(n){
//显示图片
document.getElementById('pic').src = n + ".jpg";
//立即停止间隙函数
stop_pic();
//序号背景色发生变化
//全部序号"暗"下来
var lis = document.getElementsByTagName('li');
for(var j = 0; j < lis.length; j++){
lis[j].style.background = "green";
}
//当前序号背景色高亮显示
document.getElementById('xu' + n).style.background = "yellow";
//让图片切换与当前序号一致 计数器与当前序号一致就可以
i = n;
}

求纯js 图片切换代码，最好带注释！
现在所有图片都是放在images文件家里的。 你的图片要是不是放在images文件夹里的话，比如要放在tupian文件夹里，你就在dw里替换所有images字符为tupian，就能显示小箭头了啊
