On this page, https://dev.twitter.com/docs/api/1.1/get/users/profile_banner the example result shows urls returned for different sizes, but there is no file type attached to the url - given that it could be png, jpg, gif, JPEG, etc, what should I use?
The page also mentions: "This method can be used instead of string manipulation on the profile_banner_url returned in user objects" - however I have yet to find a user object that returns "profile_banner_url". It doesn't exist in GET users/show, or at least not in the example JSON result. What user object does it get returned in?
Thanks for your help.
