C#

I'm creating some very large images in .net and i'm using JPEG compression to get the file size down. However, if the image exceeds 65,000(ish) pixels in either width or height, I can no longer use jpeg compression. Is there a max dimensions limit for JPEG?

the exception being thrown is:

System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+.
   at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)

the code that is saving the image:

    public static void SaveImage(ref Bitmap b, string fName)
        {
            long quailty = 75;
            ImageCodecInfo jpgEncoder = getEncoder(ImageFormat.Jpeg);
            Encoder myEncoder = Encoder.Quality;
            using (EncoderParameters myEncoderParameters = new EncoderParameters(1))
            {
                using (EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, quailty))
                {
                    myEncoderParameters.Param[0] = myEncoderParameter;
                    b.Save(fName, jpgEncoder, myEncoderParameters);
                }
            }
        }

in the case of the above exception the image is 2,000x100,000 the magic number seems to be in the 65k range, both width and height.  Like, I can do 4,000x55,000 but not 2x70000.
