i haven't actually written code to upload profile images recently, but what i would try is the following (and i apologise if i'm slightly incorrect as i'm doing this from memory):
> 1. What all parameters should be part of the signature base string? > oauth_consumer_key oauth_signature_method oauth_timestamp oauth_nonce oauth_version oauth_token of course, the request type and URL comprise the block that needs to be signed 2. Where should the parameters and the signature be placed in the > request stream? > the authorization header would be the best place to stick it. > 3. How should the file data be sent? multipart/form-data, i believe. -- Raffi Krikorian Twitter Platform Team http://twitter.com/raffi
