        //then save it to the Folder
        FileUpload1.SaveAs(Server.MapPath(imgPath));

        //get the size in bytes that
        int imgSize = FileUpload1.PostedFile.ContentLength;

        //validates the posted file before saving
        if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
        {
            if (FileUpload1.PostedFile.ContentLength > 5120) // 5120 KB means 5MB

            param[0].Value = name;
            param[1].Value = size;
            param[2].Value = path;

            for (int i = 0; i < param.Length; i++)
            {

You put your StartUpLoad() method inside your page load method which will not work, those need to be seperated.
