好代码，
不过可不可以把你的代码封装一下？给他指定一个div，一个图片src数组就可以run了。
我给你个简单的例子<html>
<head>
<title>Plot</title>
<style type="text/css">
body{
margin: 0px;
padding: 0px;
}
</style> </head>
<body onload="">
<div id="pic" style="height: 200px; width:300px; border: solid red 1px;overflow: hidden">
<img src="http://avatar.profile.csdn.net/2/5/E/2_sunxing007.jpg" />
</div>
<div id="words" style="height: 200px; width:300px; border: solid red 1px; display: none;overflow: hidden">
here is some word,here is some word,here is some word,here is some word,here is some word,here is some word,
here is some word,here is some word,here is some word,here is some word,here is some word,here is some word,
here is some word,here is some word,here is some word,here is some word,here is some word,here is some word,
</div>
</body>
<script>
var isPic = true;

setInterval(function(){
if(isPic){
document.getElementById('pic').style.display = "none";
document.getElementById('words').style.display = "";
isPic = false;
}
else{
document.getElementById('pic').style.display = "";
document.getElementById('words').style.display = "none";
isPic = true;
}
}, 1000)
</script>
</html>
