Converting image to base64 String? Help with code!

[jmcilhinney]

The way to write text to a Stream is with a StreamWriter, e.g.

Using writer As New StreamWriter(myStream)
    writer.Write(myString)
End Using

Try that first and, if it doesn't work, you may find that you have to use the StreamWriter constructor that takes an Encoding object as a parameter and specify Encoding.ASCII or Encoding.Unicode.
