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：

< 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>
