uploading multiple image

Dear Experts,
I am uploading multimple file with flash uploader but i am not able to collect all images name in list.
Plesae check my coed and tell me where i am wrong.
i have one if condition in my code and i am making a session and checking session is not null if its not null my if condition should fire and list can increase till my images not get uploaded.

<script type="text/javascript">
$(window).load(
    function() {
    $("#<%=FileUpload1.ClientID %>").fileUpload({
        'uploader': '../Scripts/uploader.swf',
        'cancelImg': '../images/cancel.png',
        'buttonText': 'Browse Files',
        'script': '../Upload.ashx',
        'folder': '../uploads',
        'fileDesc': 'Image Files',
        'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
        'multi': true,
        'auto': true
       
    });
   }
);
</script>

//i am using the above script to call below code

<%@ WebHandler Language="C#" Class="Upload" %>

using System;
using System.Web;
using System.IO;
using OnlineSystems;
using System.Collections.Generic;
using System.Web.SessionState;


public class Upload : IHttpHandler, IRequiresSessionState, IReadOnlySessionState
{

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
        context.Response.Expires = -1;
        try
        {
            HttpPostedFile postedFile = context.Request.Files["Filedata"];

            string savepath = "";
            string tempPath = "";
            tempPath = System.Configuration.ConfigurationManager.AppSettings["FolderPath"];
            savepath = context.Server.MapPath(tempPath);
            string filename = DateTime.Now.ToString("ddMMyymmss") + postedFile.FileName.Replace(' ', '_');

            blEventImage obj = new blEventImage();
            obj.title = filename.ToString();

//if condition not working each time its goin in else
            if (HttpContext.Current.Session["Imgs1"] != null)
            {
                List<blEventImage> lst = new List<blEventImage>();
                lst = (List<blEventImage>)HttpContext.Current.Session["Imgs1"];
                lst.Add(obj);
                HttpContext.Current.Session["Imgs1"] = lst;
            }
            else
            {
                List<blEventImage> lst = new List<blEventImage>();
                lst.Add(obj);
                HttpContext.Current.Session["Imgs1"] = lst;
            }

            if (!Directory.Exists(savepath))
                Directory.CreateDirectory(savepath);

            postedFile.SaveAs(savepath + @"\" + filename);
            context.Response.Write(tempPath + "/" + filename);
            context.Response.StatusCode = 200;


        }
        catch (Exception ex)
        {
            context.Response.Write("Error: " + ex.Message);
        }


    }

    public bool IsReusable
    {
        get
        {
            return false;
