实现页面图片阴影特效技巧三则 

第一种 利用图象编辑软件

最常用的图象编辑软件是Photoshop,制作过程如下：

1、选取一张图片；

2、打开Photoshop,为该图片建立一背景复本图层；

3、对该图层进行描边和阴影设置；

4、调整画布大小；

5、将图片保持为jpg文件。见下图：

第二种 利用表格制作

请参看下列代码：

< html>
< head>
< title>表格图片阴影< /title>
< meta http-equiv="Content-Type" content="text/html; charset=gb2312">
< /head>

< body bgcolor="#FFFFFF" text="#000000">
< table width="263" border="0" cellspacing="0" cellpadding="0" height="203">
< tr>
< td valign="top" width="243" height="183" colspan="2" rowspan="2">< img src="sample.jpg" width="240" height="180">< /td>
< td width="20" height="20">< /td>
< /tr>
< tr>
< td width="20" height="163" bgcolor="#000000" style="filter:Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0) Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=0, StartY=10, FinishX=0, FinishY=0)">< /td>
< /tr>
< tr>
< td width="20" height="20">< /td>
< td width="223" height="20" bgcolor="#000000" style="filter:Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=0, StartY=0, FinishX=0, FinishY=100) Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=10, StartY=0, FinishX=0, FinishY=0)">< /td>
< td width="20" height="20" bgcolor="#000000" style="filter:Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=0, StartY=0, FinishX=0, FinishY=100) Alpha(Opacity=100, FinishOpacity=0, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0)">< /td>
< /tr>
< /table>
< /body>
