CSS code

body{    font-family: Verdana, Arial, Helvetica, sans-serif;    font-size: 12px;    text-align: center;    color: #000000;    background-color: #FFFFFF;    background-image: url(../img/1111.jpg);    background-repeat: repeat-y;    background-position: center;    margin: 0;}

编辑器里面点击设计的时候是显示的。浏览器浏览的时候就不显示出来了

------解决方案--------------------------------------------------------
你在页面中写<img src="../img/1111.jpg">能出来吗

如果不能出来，问题有3
1，路径是错误的
2，没有匿名访问权限
3，图像格式不是rgb
------解决方案--------------------------------------------------------
没有权限可以在web。config里面设置
<configuration>
