as3 posting an image to twitter

[georgeprins]

Hi

I am currently building an air app (as3) that need to post an image to Twitter. I am using the code below to locate a file (.jpg) and then post it to twitpic.
I get an invalid password reply from the API. Can someone please help with the invalid password reply. You can enter your usename and password in the variables private var TWITTER_USERNAME = “”; private var TWITTER_PASSWORD = “”;

package com.twitter
{
import flash.events.DataEvent;
import flash.events.Event;
import flash.filesystem.File;
import flash.net.FileFilter;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
import flash.net.URLVariables;

public class TwitPic
{
    private var _file:File;
	private var TWITTER_USERNAME = "";
	private var TWITTER_PASSWORD = "";
   
    public function TwitPic()
    {
		trace("twitpic")
        _file = new File();
        _file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA,uploadCompleteDataHandler);
        browse();
    }
    private function browse():void {
        _file.addEventListener(Event.SELECT, fileSelected);
        _file.browse( new Array( new FileFilter( "Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg;*.jpeg;*.gif;*.png" ) ) );
    }
   
    private function fileSelected(event:Event):void {
        var urlRequest:URLRequest = new URLRequest("http://twitpic.com/api/upload");
       
        // The API requires the request be sent via POST
        urlRequest.method = URLRequestMethod.POST;
       
        // Enter a valid Twitter username / password combination
        var urlVars:URLVariables = new URLVariables();
        urlVars.username = TWITTER_USERNAME;
        urlVars.password = TWITTER_PASSWORD;
        urlRequest.data = urlVars;
       
        // The API requires the file be labeled as 'media'
        _file.upload(urlRequest, 'media');
    }
   
    private function uploadCompleteDataHandler(event:DataEvent):void
    {
		trace("twitpic event" + event);
		trace("twitpic event.text=" + event.text);
        var resultXML:XML = new XML(event.text);
       
        // Trace the path to the resulting image tiny url (mediaurl)
        trace("twitpic result="+resultXML.child("mediaurl")[0]);
    }
}

}
