图片下面有空白(3px左右)
问题说明:
<div   id= "announcell "> <img   src= "images/index_02.jpg "   width= "8 "   height= "333 "> </div>       这里写在一行就没有空白了

<div   id= "announcelm1 "> <img   src= "images/index_03.jpg "   width= "240 "   height= "43 "> </div>         但是这下面的就不行了

快救我吧,期待中....

------解决方案--------------------
css中加这个：
img {
display:block;
}

还有，代码不是搂主这么写的，你这样写等于是个“table”者，干脆用回table算了……

这样试试：
<div id= "announce ">
<div>
<h2> </h2>
<p> d </p>
<p> e </p>
<p> c </p>
</div>
</div>

<style type= "text/css ">
* {
padding:0;
margin:0;
}
#announce {
background:url(images/index_02.jpg) 0 0 no-repeat;
padding-left:8px;
height:333px;
}
#announce div {
background:url(images/index_04.jpg) right 0 no-repeat;
padding-right:14px;
}
#announce h2 {
background:url(images/index_03.jpg) no-repeat;
width:240px;
height:43px;
}
</style>

虽然不一定就严格符合web标准，但是代码简洁多了，表现也和结果分离
