Owned by POST (Sad Day!)

Hey All,

So I'm working on using the Flickr API and uploading a file. Problem is, somehow I'm not formatting the POST output correctly. Always am getting "POST is too Large" and after some troubleshooting I think the content-length is off.

Needs to look similar to this: Upload Example

Any ideas?
