How to create new post with photo attached in WordPress using XMLRPC?

Question

Anyone knows how to create new post with photo attached in WordPress using XMLRPC?

I am able to create new post and upload new picture separately,

Answer 1

As of Wordpress 3.5, newmediaobject now recognizes the hack semi-natively.

it is no longer necessary to hack class-wp-xmlrpc-server.php.

Instead, your xml-rpc client needs to send the post number to a variable called post_id. (Previously it was just the variable 'post')

Hope that helps someone out.
