第二步:把如下代码加入<body>区域中:
<form>
图片1的名字：
<INPUT TYPE="text" NAME="bilden" class="pt9" value="mouseoutpic">
<BR>
图片1的路径：
<INPUT TYPE="text" NAME="srcen" class="pt9" value="images/pic1.gif">
<BR>
图片1的宽度：
<INPUT TYPE="text" NAME="widden" class="pt9" value="100">
<BR>
图片1的高度：
<INPUT TYPE="text" NAME="hojden" class="pt9" value="50">
<P> 图片2的名字：
<INPUT TYPE="text" NAME="bildtva" class="pt9" value="mouseoverpic">
<BR>
图片2的路径：
<INPUT TYPE="text" NAME="srctva" class="pt9" value="images/pic2.gif">
<BR>
操作的名字 ：
<INPUT TYPE="text" NAME="bildnmn" class="pt9" value="first_pic">
<BR>
<INPUT TYPE="BUTTON" VALUE="生成代码" OnClick="skrivut(this.form)" class="pt9">
</FORM>
<P>
<P>说明：图片1==》mouse out时的图片，正常显示时。图片2==》mouse over时的图片。图片的名字和操作的名字可以随便取。有所区别即可。
<P>2个图片的尺寸必须一致才可以。
