I wish to upload media from an external panel, which wordpress functions should I touch? Also, I would also need the function which sets the blog and post to insert into. Should I just use the set_blog_id function from the wpdb class to set the blog?
I also tried using the pop-up flash uploader of the wordpress panel but I can't seem to set the blog and post so it normally uploads it towards the main blog which has an id of 1.
Any piece of advice would be greatly appreciated. Thanks! :)
