To resize down a image and get smaller sizes just make the changes below

    bmpOut = new Bitmap(lnNewWidth, lnNewHeight, **System.Drawing.Imaging.PixelFormat.Format24bppRgb**);

     Graphics g = Graphics.FromImage(bmpOut);

as you above a set the imagem to Format24bppRgb PixelFormat.

and when you save the file, you set the ImageFormat also. Like this:

bmpOut.Save(PathImage, System.Drawing.Imaging.ImageFormat.Jpeg);
