In this series of articles, I am going to introduce each of the plugins I have developed for ClassicPress, a hard-fork of WordPress, which was originally created to provide an alternative, yet compatible, CMS without the Gutenberg block editor.
The 19th plugin is Gallery From Folder.
Gallery From Folder is a simple plugin which will read a folder and display a gallery of all thumbnails with links to the original full-size image.
The [gallery-from-folder] shortcode can be provided with either an alt_id parameter referencing a specific name or a post_id for a ClassicPress post.
An example of the shortcode is [gallery-from-folder alt_id="sample-gallery"].
