Excellent! Thank you! Here's the final working code:
System.Drawing.Bitmap Image = new Bitmap( @"C:\test.jpg" );
System.IO.MemoryStream Memory = new MemoryStream();
Image.Save( Memory, System.Drawing.Imaging.ImageFormat.Jpeg );
Memory.Seek( 0, SeekOrigin.Begin );
Service.Update
(
Contact.PhotoEditUri,
Memory,
"image/jpeg",
null
);
