Aha! I got stuck with the same problem. No way, you will need to fetch the captcha, and it is random!
Check more details here: http://orkut-os-client.googlecode.com/hg/README <http://orkut-os-client.googlecode.com/hg/README>"4. Captcha handling The API may occasionally throw Captchas to validate that it's indeed a human issuing the requests, for example, for the very frequent scrap posts. Captchas can be expected any time and, in general, every transaction should ideally be checked for a Captcha challenge. A brief overview of how to handle a captcha can be found here: http://code.google.com/p/orkut-os-client/source/browse/java/src/com/google/orkut/client/api/CaptchaTxFactory.java. A typical image URL returned from the challenge is /social/pages/captcha?xid=yyy. That must be prefixed with the endpoint URL (http://www.orkut.com), and then the Captcha image must be retrieved from the complete URL (http://www.orkut.com/social/pages/captcha?xid=yyy) using OAuth. For a more concrete example, please refer to the source of our reference implementation -- Fotoscrapr -- that can be found at: http://code.google.com/p/orkut-os-client-greetings/source/browse/src/com/google/orkut/client/api/samples/greetings/server/servlets/CaptchaServlet.java."
