This plugin extends the default XML-RPC server API with one new method for specifying author and parent post of remotely uploaded attachment files.
<ol>
<li>preserved backward compatibility with the basic method wp.uploadFile</li>
<li>simple usage, just replace with wp_extended.uploadFile and add 2 OPTIONAL parameters to the data struct: author (string, user_id of author) and parent (string, post_id of parent post)</li>
<li>without the optional parameters the new method is identical in behaviour with the basic method found in WordPress API of XML-RPC</li>
