Andy, you've saved me again.  Here's what I use from the 'client' end,

-----start scriptlet----------

from Shared.UoB.xmlrpclibBasicAuth import Server
import xmlrpclib, base64

def transfer2server(self, url, image, img_id,):
        s = Server(url, 'username', 'password')
        s.doimage(img_id, base64.encodestring(image))

-----end scriptlet----------

The 'doimage' method on the remote system simply has a base64.decodestring()
and then does what it wants.  In my case, manage_addImage().

Thanks very much.

tim
