Trouble uploading to twitpic

I am trying to upload a photo using the API and am having an issue that I hope you can help me with. Below, I have pasted the http request to the API (minus the twitter username/password). I am getting an error message back saying image not found, even though the image is there with the proper name "media". I have created a simple web project on my end to te开发者_如何学JAVAst to make sure the image is being encoded correctly, and it is. Is there anything in this request that you can see that would cause the api to reject this?

Thanks

Figured it out. In the Content-Type Disposition for the file upload I had this:

Content-Disposition: form-data, name="media"; filename="test.jpg"

Instead of the required this: Content-Disposition: form-data; name="media"; filename="test.jpg"

Stupid commas.
