Answer 1

<div style="background: url(Images/XiangKuang-1.gif) no-repeat; z-index:1; position:absolute;width:147px;">
<div style="padding:8px 8px 0px 7px; z-index:0; width:130px; height:150px;position:absolute;"> <asp:Image ID="Image1" runat="server" Width="130px" Height="150px" ImageUrl="~/images/quanli3.jpg"/>
</div> </div>
关键要设置绝对定位，才能应用z-index
