在后台发布系统做了一个上传图片的页面（子窗口）。现在我上传一个图片后，把值传回主窗口。现在问题是，通过window.returnValue取得图片

这是我现在弄得一个系统，有和你一样的功能。给你看看~!!我的是实现相对路径的。upfile.asp<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>

    谢谢您，不过您的实现与我得实现还有一点区别，我得是在主窗口中点击一个插入图片的链接，然后弹出一个子窗口，内容如下：
       pic_url="/images/upload/"+filename;
       //out.println("pic_url="+pic_url);
       %>
      <script language="javascript">
    alert("恭喜您，图片上传成功！");
    self.returnValue = "<img src='<%=pic_url%>'>";
      </script>
    然后在主窗口就会得到<IMG src="http://.../">的绝对地址，好像是javascript的机制问题，请赐教！
