Description

Markdown block has a shortcode called gallery. Its usage just like this:

{{< gallery album="path/to/demo" order="desc" resize_options="1024x1024" >}}

It usually works well. However, when path of an album contains capital letter, for example assets/media/albums/DEMO relative to project root, this statement will get an error like this during building:

ERROR 2022/12/17 11:55:43 Unable to load gallery `media/albums/DEMO/*` in `/home/runner/work/wowchemy-md-album-bug/wowchemy-md-album-bug/content/home/markdown.md`.
Error: Error building site: logged 1 error(s)
