1.<asp:Image>标签的使用Loginer.images是图片的路径

   this.images.ImageUrl = "showImg.aspx?imgFile="+ Loginer.images;

2.添加一个新的页面showImg.aspx,在后台代码写

private string file = string.Empty;        protected void Page_Load(object sender, EventArgs e)        {            file = Request.QueryString["imgFile"].ToString();            FileStream stream = new FileStream(file, FileMode.Open);            //获取流的的长度            long FileSize = stream.Length;            byte[] Buffer = new byte[(int)FileSize];            stream.Read(Buffer, 0, (int)FileSize);            stream.Close();            Response.BinaryWrite(Buffer);            stream = null;        }

显然这是把他当做一种请求处理的
