如何从数据库中获取图片。

数据库中是存储的图片位置，但是我现在已经把图片的位置获取出来了，不晓得如何转成图片显示在页面
这事以下代码。
using System;
using System.Collections.Generic;

using System.Data;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Mobile_Content_BLL;

namespace Mobile_Content.Mobile
{
 public partial class FoodStuff_type1 : System.Web.UI.Page
 {
 public string bb = string.Empty;
 public string Content = string.Empty;
 protected void Page_Load(object sender, EventArgs e)
 {
 if (!IsPostBack)
 {
 Contents();
 }
 }

 public void Contents()
 {
 if (null == Request["id"])
 {
 Response.Write("");
 Response.End();
 }

 int id = Convert.ToInt32(Request["id"]); //接收ID
 StringBuilder str = new StringBuilder();
 DataTable dt = new Mobile_Content_BLL.Mobile_Manager.Mobile_Manager().FoodStuff_Type(id); //读取数据
 if (dt.Rows.Count != 0)
 {
 //byte[] bPhoto = dt.Rows[0]["pics"] as byte[];
 string name = dt.Rows[0]["name"].ToString();
 string bieming = dt.Rows[0]["bieming"].ToString();
 string tupian = dt.Rows[0]["pics"].ToString(); //这里是图片获取出来的只是路径
 string pinyin = dt.Rows[0]["pinyin"].ToString();
 string gongxiao = dt.Rows[0]["gongxiao"].ToString();
 string googfor = dt.Rows[0]["goodfor"].ToString();
 string badfor = dt.Rows[0]["badfor"].ToString();
 string feature = dt.Rows[0]["feature"].ToString();
 string desc = dt.Rows[0]["desc"].ToString();
 Content = "<table style=\"width:100%\"><tr><td style='width:100px'>[名称] " + name + "</td></tr> <tr><td>[别名] " + bieming + "</td></tr><tr><td>[图片] " + tupian + "</td></tr><tr><td>[拼音] " + pinyin + "</td></tr><tr><td>[功效] " + gongxiao + "</td></tr><tr><td>[适宜] " + googfor + "</td></tr><tr><td>[禁忌] " + badfor + "</td></tr><tr><td>[特点] " + feature + "</td></tr><tr><td>[描述] " + desc + "</td></tr></table>";
 this.Response.Write(Content);
 }
 else
 {
 Response.Write("lock");
 Response.End();
 }
 bb = str.ToString();
 Response.Write(bb);
 Response.End();

 }
 }
} --------------------编程问答-------------------- 用控件显示出来，比如Image控件
Image1.ImageUrl="图片路径"; --------------------编程问答-------------------- Content = "<table style=\"width:100%\"><tr><td style='width:100px'>[名称] " + name + "</td></tr> <tr><td>[别名] " + bieming + "</td></tr><tr><td>[图片] <img src=" + tupian + " /></td></tr><tr><td>[拼音] " + pinyin + "</td></tr><tr><td>[功效] " + gongxiao + "</td></tr><tr><td>[适宜] " + googfor + "</td></tr><tr><td>[禁忌] " + badfor + "</td></tr><tr><td>[特点] " + feature + "</td></tr><tr><td>[描述] " + desc + "</td></tr></table>";
