<img src = "be.bmp" usemap = "#blockman">
是图像上定义了热区
而热区的具体定义就是下面这个
<map name="blockman">
<area coords = "80,88,120,125" href="ch04_02.htm" onMouseOver = "myEye()">
<area coords = "169,88,208,125" href="ch04_03.htm" onMouseOver = "myEye()">
<area coords = "124,147,165,181" href="ch04_04.htm" onMouseOut = "myNose()">
<area coords = "92,210,192,228" href="ch04_05.htm" onMouseOut = "myMouth()">
<area coords = "6,4,292,266" href="ch04_06.htm" onMouseOver = "onHead()">
</map>
<img src = "be.bmp" usemap = "#blockman">
中的 usemap = "#blockman"是指定在那个图片上加什么样的热点操作。
<map name="blockman"></map>是设置热点操作。
至于老加的那句话，没有去深入研究过，个人认为
