显示已上传的图像到gridview

Question

我能够看到我的gridview上的jpeg文件，但我想要的是看到图像本身。这里是我的按钮代码：

protected void Button1_Click(object sender, EventArgs e) 
    { 
     if (FileUpload1.HasFile) 
     { 
      string bname = TextBox1.Text; 
      string city = DropDownList1.SelectedValue.ToString(); 

      string filename = Path.GetFileName(FileUpload1.FileName); 
      FileUpload1.SaveAs(Server.MapPath("~/Images/") + filename); 


      Execute("INSERT INTO building VALUES('" + bname + "','Binay',1, '" + filename + "')"); 
      Label3.Text = "sucess"; 

      SqlDataAdapter sda = new SqlDataAdapter("Select * from building",ConnectionString); 
      DataTable dt = new DataTable(); 
      sda.Fill(dt); 
      GridView1.DataSource = dt; 
      DataBind(); 
     } 
     else 
     { 
      Label3.Text = "upload image"; 
     } 


    } 

任何建议都会有很大的帮助。谢谢！
