Post image to facebook wall

I'm trying to post a Texture2d within Unity to Facebook.

I have the proper access token and album id, but it doesn't want too upload.

I don't get any web or Facebook error codes.

This is what i'm working with:

 IEnumerator _Post()
 {
     WWWForm form = new WWWForm();
         
     form.AddBinaryData("source", texture.EncodeToPNG(), texture.name + ".png", "image/png");
         
     string url = string.Format("https://graph.facebook.com/{0}/photo?access_token={1}", albumId, accessToken);
         
     Debug.Log(url);
         
     WWW web = new WWW(url, form);
     yield return web;
         
     Debug.Log(web.error);    
     Debug.Log(web.text);
 }

From the Debug.Log's I get Null and True
