+The img tag's source should be specified using **cid:mxcid** prefix before the source file to have this image added as inline image. Then create Attahcment with the Position attribute set to *ENUM_AttachmentPosition.Inline*. Associate the Attachment with EmailMessage and you should be able to send this email using *SUB_SendEmail* Microflow.
