protected void Button1_Click(object sender, EventArgs e)
    {
        string[] filesindirectory = Directory.GetFiles(@"E:\ra");
        int i = 1;
        foreach (string s in filesindirectory)
        {
            Image img = new Image();
            img.ID = "image" + i.ToString();
            img.ImageUrl = s;
            img.Visible = true;
            Page.Controls.Add(img);
            i++;
