Hi Gerard, Though I know it doesn't sound like it should matter, can you try your request against Twitpic after inserting spaces after each comma in your Authorization Header? Also want to make sure that you aren't executing your verify_credentials request in the preparation sequence (calling the resource prior to TwitPic calling it would invalidate it).
