I’m not proud of this solution, but then again I am not a coder, Jim.
Since I couldn’t get the folder name any other way, I’m gonna use the file name as the folder (issue-1, issue-2, etc)
{{ $image_path := "themes/magazine/static/img/covers/menu/" }}
{{ $images := readDir $image_path }}
{{ range $images }}
{{ $link := trim .Name ".jpg" }}
<a href="{{ $link }}"><img src="../img/covers/menu/{{ .Name }}" class="img-fluid w-100"></a>
{{ end }}
Angels will cry, I know. But what else can I do? It works!
