[GSharp69]

Hi

i have tried to put images in a docx with open xml
he creates the docx but no images are shown in the document

i use this code to put images:

PackagePart partPicture = document.CreatePart(packageOutput, uriPicture, "image/jpeg");

            using (Stream targetStream = partPicture.GetStream()) 
            {
                using (FileStream sourceStream = new FileStream(@"c:\Joker2.jpg",FileMode.Open, FileAccess.Read))
                {
                    byte[] buffer = new byte[1024];
                    int nrBytesWritten = sourceStream.Read(buffer, 0, 1024);
                    while (nrBytesWritten > 0)
                    {
                        targetStream.Write(buffer, 0, nrBytesWritten);
                        nrBytesWritten = sourceStream.Read(buffer, 0, 1024);
                    }
                }
            }
