1. Create a System.IO.MemoryStream object.
2. Create a System.IO.FileStream object
3. Save image into MemoryStream
4. Read bytes[] from the MemoryStream
5. Save the image file with FileStream
And Here is the C# sample code;

using System.Drawing.Imaging;
using System.Drawing;
using System.IO;
public static void SaveJpeg
(string path, Image img, int quality)
{
EncoderParameter qualityParam
= new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality);
ImageCodecInfo jpegCodec
= GetEncoderInfo(@"image/jpeg");
EncoderParameters encoderParams
= new EncoderParameters(1);
encoderParams.Param[0] = qualityParam;
System.IO.MemoryStream mss = new System.IO.MemoryStream();
System.IO.FileStream fs
= new System.IO.FileStream(path, System.IO.FileMode.Create
, System.IO.FileAccess.ReadWrite);
img.Save(mss, jpegCodec, encoderParams);
byte[] matriz = mss.ToArray();
fs.Write(matriz, 0, matriz.Length);
mss.Close();
fs.Close();
}
