(PHP ActiveX) Outlook --Download MIME Embedded Images in an HTML EmailDemonstrates how to download the MIME embedded images for a particular HTML email message. The code for downloading the embedded HTML images is the same as for downloading attachments. When an HTML email has embedded images (and no real attachments), the JSON returned when listing the message will indicate "hasAttachments": false. However, you can still use the URL for getting attachments to get the embedded images. Note: This example requires Chilkat v9.5.0.67 or greater. This example applies to: Exchange Online | Office 365 | Hotmail.com | Live.com | MSN.com | Outlook.com | Passport.com
