代码块：

using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Web;
    
    namespace SoonnetWebSite
    {
        /// <summary>
        /// Handler1 的摘要说明
        /// </summary>
        public class Handler1 : IHttpHandler
        {
            private const string DEFAULTIMAGE_URL = "/SGL_Images/Userlogo_Smail_1173.jpg";
            public void ProcessRequest(HttpContext context)
            {
                string imgPhysicalPath = context.Request.Url.ToString(); System.Drawing.Image image = null;
    
                if (File.Exists(imgPhysicalPath))
                {                         //为空
                    image = System.Drawing.Image.FromFile(context.Request.PhysicalPath);
                }
                else
                {             //如果图片不存在，放上默认的图片           
                    image = System.Drawing.Image.FromFile(context.Server.MapPath(DEFAULTIMAGE_URL));
                }
                //设置输出的类型      
                context.Response.ContentType = "image/jpeg";
                //把图片保存到输出流里      
                image.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
                image.Dispose();
            }
    
            public bool IsReusable
            {
                get
                {
                    return false;
                }
            }
        }
    }

配置文件web.config

大功告成。
