Description Piotr Doroszewski 2025-06-12 16:08:49 UTC 
OBSERVED RESULT
When a directory contains two to four images, all of them are shown in the thumbnail. When it contains more than four image, some four of them are shown.

By "images" I don't mean only images, but also other kinds of files with previews, like Blender models or text documents, etc.

EXPECTED RESULT
I wish that only the "main" image appeared in the thumbnail if it is present.

It is a custom that such a file should be named `folder.jpg` or `cover.jpg`, but I would also add support for PNG variants.
