[profile_ids required] media optional [array] associative array
An associative array of media to be attached to the update, currently accepts link, description, title, picture and thumbnail parameters. For image-based updates, picture and thumbnail parameters are both required. Please note that some of the fields might not be required depending on what profile(s) you're posting to, and they will be silently ignored. For example, if you're posting to a Twitter profile, many of the media parameter fields aren't used - in fact the only ones that are are 'photo' and 'thumbnail'. If you don't see some of the media parameters you specified in the response to your request, it simply means that they were not required and ignored.
