Comment (by Rezzy-dev):

 Solution found!

 Claws Mail relies on /etc/mime.types for file MIME type associations when
 adding attachments to mail.

 The solution is to create the /opt/local/etc/mime.types configuration/text
 file and populate it with:

 {{{
 image/jpeg    jpg jpeg
 image/png    png
 image/gif    gif
 image/webp    webp
 }}}

 After this, the images for attached image files display as excepted in
 mail (Claws Mail assigns the correct MIME type to the attachments).
