                    .HTMLBody = "ICD wanted to wish you a Happy Birthday Today!!!"
                    'Change Display to Send if you want the messages sent automatically'
                    .Send

            End If

The HTML body must refer to the image through the src:cid attribute (<img src="cid:xyz">), where xyz is the value of the PR_INTERNET_CONTENT_ID property (DASL name http://schemas.microsoft.com/mapi/proptag/0x662A001F) set on attachment using Attachment.PropertyAccessor.SetProperty.
