Inserts an attachment.

If you set the 'ID' in the $args parameter, it will mean that you are updating and attempt to update the attachment. You can also set the attachment name or title by setting the key 'post_name' or 'post_title'. You can set the dates for the attachment manually by setting the 'post_date' and 'post_date_gmt' keys' values. By default, the comments will use the default settings for whether the comments are allowed. You can close them manually or keep them open by setting the value for the 'comment_status' key.
