Jeni,
Have a look at
http://msdn.microsoft.com/downloads/samples/internet/default.asp?url=/do
wnloads/samples/internet/behaviors/library/webservice/default.asp for a
simple JavaScript base64 function. Add a couple of lines to write the
result to a file and you are sorted. Or for the external method have a
look at uuencode
