Hello. for showing photo in my site. i am using Handler(.NET 3.5) to read from DB a and show it in DataList. But when i uploaded the site photos are shown slow.
Please look at the site:[^]

and the code that i am using:
<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
using System.Data.SqlClient;
public class Handler : IHttpHandler {
    SqlConnection myConnection;
    SqlCommand cmd;
    public Handler()
        myConnection = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["myDB"].ConnectionString);
        cmd = new SqlCommand("", myConnection);
    public void ProcessRequest (HttpContext context) {
            string sql = "Select TPImage,id,Image_Type from TProduct where Id=@Id";
            cmd.CommandText = sql;
            cmd.Parameters.Add("@Id", System.Data.SqlDbType.Int).Value =    context.Request.QueryString["Id"];
            SqlDataReader dr = cmd.ExecuteReader();
            context.Response.ContentType = dr["Image_Type"].ToString();
            //باید برای عکس یکی از این فایل ساخته شود تا که بتونی هر عکس رو جدا لود کرد.
        catch (Exception ex)
    public bool IsReusable {
        get {
            return false;

1. Consider generating thumbnails for previews. On a link above to display preview about 100x100 pixels size you are spooling 1M+ pictures.

2. Imagine your website channel load if it becomes popular

3.Strictly saying, it is not recommended to store pictures of a such big size in the database.

4. consider supporting http caching as well.
