PHP Function to Create Wordpress Posts and Featured Images

I need a php function created that will insert a post and featured image into a Wordpress site. Please read the requirements carefully before bidding. Function parameters: * wordpress url * user * password * post title * post content * post tags * post categories * post author * post type * url of an image (this will be the URL of an image on a remote server) Function operations. Things the function will do: * create a post in wordpress with the input provided * retrieve the image file from the image url * upload the image to wordpress * set the image to be the "featured image" for the post in wordpress Wordpress already includes a function called wp_insert_post, so most of this project is easy using that function. However the key part of this project is uploading an image and setting the image as the featured image associated with the post that was just created.
