Adding images to automated emails

While creating an automation to send an email when a new item is created on a table, an image should be able to added to the email. For now, you can only add an image as a attachment document, however it’s better to add in into the mail body. Also, the attached document can only be opend by Monday users, for now. But, It should be open to everbody. I am tying to create an automated welcome email to my clients, but I cannot add an welcome-image to my email.
