this is my code (updating code it is a edit page and i am updating)

  if (fupPhoto.FileName != string.Empty)
        {
            filename = ran(fupPhoto.FileName);
            FileInfo fi = new FileInfo(filename);
            string ext = fi.Extension.ToUpper();
            string path = Server.MapPath("../User/photo/thumb/");              
            if (ext == ".JPEG" || ext == ".JPG" || ext == ".PNG" || ext == ".BMP" || ext == ".GIF")
            {
                fupPhoto.PostedFile.SaveAs(path + filename);
                Bitmap src = Bitmap.FromStream(fupPhoto.PostedFile.InputStream) as Bitmap;
                Bitmap result = ResizeBitmap(src);
                SizeMgt(filename);
                System.Drawing.Bitmap img = new System.Drawing.Bitmap(result, newwid, newhgt);
                System.Drawing.Imaging.ImageCodecInfo jpegcodec = null;
                System.Drawing.Imaging.EncoderParameters EncParams;
                foreach (System.Drawing.Imaging.ImageCodecInfo codec in System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders())
                {
                    if (codec.MimeType == "image/jpeg")
                    {
                        jpegcodec = codec;
                        break;
                    }
                }

                EncParams = new System.Drawing.Imaging.EncoderParameters(1);
                EncParams.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 20L);

                img.Save(path + newfilename, jpegcodec, EncParams);
                img.Dispose();

            }
        }
        else
        {
            newfilename = myphot; 
        }

                cmd = new SqlCommand("sp_uptreg", conn);
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@tregno", lblregno1.Text);
                cmd.Parameters.AddWithValue("@catid", ddlCategory.SelectedItem.Value);

                    int a = cmd.ExecuteNonQuery();

I think that this function fails, if the file all ready exist !

 fupPhoto.PostedFile.SaveAs(path + filename);

so you need to delete it first (if exist).

You can use the FileInfo(path + filename), to see if FileExist and delete it.

From the SaveAs, you see that have the Create Option. So the procedure fails if the file all ready exist.

public void SaveAs(string filename)
{
    if (!Path.IsPathRooted(filename) && RuntimeConfig.GetConfig().HttpRuntime.RequireRootedSaveAsPath)
    {
        throw new HttpException(SR.GetString("SaveAs_requires_rooted_path", new object[] { filename }));
    }
    FileStream s = new FileStream(filename, FileMode.Create);
    try
    {
        this._stream.WriteTo(s);
        s.Flush();
    }
    finally
    {
        s.Close();
    }
}

I suggest also to use the using keyword on the objects that need dispose.

        using (Bitmap src = Bitmap.FromStream(fupPhoto.PostedFile.InputStream) as Bitmap)
        {
            //Bitmap result = ResizeBitmap(src);
            //SizeMgt(filename);                
            using (System.Drawing.Bitmap img = new System.Drawing.Bitmap(result, newwid, newhgt))
            {
                System.Drawing.Imaging.ImageCodecInfo jpegcodec = null;
                System.Drawing.Imaging.EncoderParameters EncParams;
                foreach (System.Drawing.Imaging.ImageCodecInfo codec in System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders())
                {
                    if (codec.MimeType == "image/jpeg")
                    {
                        jpegcodec = codec;
                        break;
                    }
                }

                EncParams = new System.Drawing.Imaging.EncoderParameters(1);
                EncParams.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 20L);
                newfilename = "new" + filename;
                img.Save(path + newfilename, jpegcodec, EncParams);
                img.Dispose();
            }
            src.Dispose();
        }
