The API currently returns http://s3.amazonaws.com/twitter_production/profile_images/93621634/Untitled-1_normal.jpg as the profile_image_url for me (http://twitter.com/users/show.xml? screen_name=dburkes). Amazon says this URL isn't valid.
Furthermore, if I change my profile image via twitter.com, or delete it via twitter.com, the API still returns the same bogus profile_image_url. As a result, my profile image looks fine on twitter.com, but any API client like Tweetie or Twitterific shows a blank profile image. Thoughts? Best, Danny Burkes
