#66581: No images displayed in standard mail (image viewer settings not working)

Component:  ports      |    Version:  2.8.0
 Keywords:             |       Port:  claws-mail
-----------------------+------------------------
 Claws Mail has options in the Preferences under the "Message View" header
 for the built-in "Image Viewer". The problem is none of these seem to be
 currently working in the port -- none of the images are displayed in
 regular emails (non-HTML).

 I'm not sure if this is a dependency issue (if Claws Mail is relying on a
 library that isn't present to render/display the images), if it's a
 bug/omission in the port, or if I'm missing something.

 The logs don't seem to show anything wrong either -- Claws Mail doesn't
 seem to realise there is a problem.

 To replicate the issue, tick all the Image Viewer settings to be on, and
 relaunch Claws Mail. If there are image attachments in an email, Claws
 Mail won't show them in the mail (only links to the files).
