PHPMailer::addEmbeddedImage() public WP 1.0

Add an embedded (inline) attachment from a file. This can include images, sounds, and just about any other document type. These differ from 'regular' attachments in that they are intended to be displayed inline with the message, not just attached for download. This is used in HTML messages that embed the images the HTML refers to using the $cid value. Never use a user-supplied path to a file!

{} Это метод класса: PHPMailer{}

Хуков нет.
