I use wp_mail and phpmailer to send over 100 recipients the same HTML formatted message. The message is cut and pasted from Outlook Express and includes embedded images like this:
However, when I send the message the image is blank. The HTML text, on the other hand, comes thru fine.
Questions: Where is the original image pixel bytes? How do I copy the original images? Do I use phpmailer "AddEmbeddedImage" and how? What is the path name? Note: I create external attachments using phpmailer "AddAttachment" and it works fine.
The Postmaster plug-in, which sends attachments, use routines similar to phpmailer. It also uses wp-mail not wp_mail. Is this the route to go, working with raw data? Besides, it only allows one attachment.
Any help appreciated.
