When I try something like the example in http://groups.yahoo.com/group/xml-rpc/message/1409 I get Error Type: AttributeError Error Value: seek If I don't use Binary, I'm o.k. unless I use a "special" character. That doesn't last long in a JPEG image. Any suggestions? Thank you. --kyler =============== imagedata = open('/home/gunsmoke/a/laird/public-web/Kyler/images/disk0016/img_0196.jpg').read() image = xmlrpclib.Binary(imagedata) pprint(Zopesvr.test.images.manage_addImage('img_0196', image, 'dogs by stream in Aspen', '', 'image/jpeg'))
