Images not appearing in HTML mail

Debian 9
Usermin version 1.734
Webmin version 1.872
Theme version Authentic Theme 19.09-beta3

How do I enable images to show up in mail received using HTML as a preference using Authentic theme? Show inline images by defaultis set to 'Yes'.

If I switch to Gray Framed Theme, images in a mail show up, so I reckon I already have the option to display images in HTML email enabled.

Kindly advise.

Same issue, please help, it's the best theme.

Are these images that are included with the email, or loaded from a remote URL?
