Zac, I would love to do this but I can't find any documentation on how to do Oauth Echo with python-oauth2. I would gladly switch to python-ouath2 if I could find some code showing How to use it to post a picture on twitpic : http://dev.twitpic.com/docs/2/upload/
<http://dev.twitpic.com/docs/2/upload/>Any help would be greatly appreciated.
