I have found and answer to my own question. below is the code if any one its..

Below code will help you get all the image in word document.

foreach (ImagePart imagePart in doc.MainDocumentPart.ImageParts)
{
    var uri = imagePart.Uri;
    var IdR = doc.MainDocumentPart.GetIdOfPart(imagePart);
    string FileExtension = uri.OriginalString.Split('.').Last();
    var filename = uri.ToString().Split('/').Last();
    stream = doc.Package.GetPart(uri).GetStream();
    Bitmap b = new Bitmap(stream);
    string FilePath = @"C:\test"." + FileExtension;
    b.Save(FilePath);
}

Below will help you get the embedded object in word document like: Visio, MP3 video.

var IdR = doc.MainDocumentPart.GetIdOfPart(embeddedobjectpart);
string FileExtension = embeddedobjectpart.Uri.OriginalString.Split('.').Last();
FileExtension = "vsd";
stream = doc.Package.GetPart(embeddedobjectpart.Uri).GetStream();
long length = stream.Length;
byte[] byteStream = new byte[length];
stream.Read(byteStream, 0, (int)length);
string FilePath =@"C:\test"." + "." + FileExtension;
fstream = new FileStream(FilePath, FileMode.OpenOrCreate)
fstream.Write(byteStream, 0, (int)length);
fstream.Close();
