問題：如何讓首頁縮略圖顯示半透明效果？
解決：在模板相應的文章文章頻道標簽中，顯示圖像標簽的表格ID設置為“id=imgbox”，并在網頁<head>中加一如下代碼：
<SCRIPT language=JavaScript type=text/javascript>
function transpic() {
var imgNodes = document.getElementById("imgbox").getElementsByTagName("img");
for (var i=0; i<imgNodes.length; i ){
var imgNode = imgNodes[i];
imgNode.setAttribute("class","low");
imgNode.className = "low";
imgNode.onmouseover = function(){
this.setAttribute("class","high");
this.className = "high";
}
imgNode.onmouseout = function(){
this.setAttribute("class","low");
this.className = "low";
}
}
}
</SCRIPT>
