Knowledge Base: Why isn't text sent to TwitPic?
The TwitPic API (http://twitpic.com/api.do)
currently supports two methods, upload and
uploadAndPost.
Tweetie uses the upload method because there is a
lot of piping internally with respect to multiple attachments,
Twitlonger, geotagging, setting in_reply_to_status_id
and more. Using uploadAndPost would cause all of these
features to break.
Sadly, the TwitPic API only accepts a message
parameter for the uploadAndPost method. Once they add
support for it for the upload method, Tweetie can be
updated to send the associated message text along with the picture
upload.
