Hi

I was trying to work out how to best iterate a folder and with help of this forum worked out a way so thought I would share it for others (as I am long time developer but newish to OctoberCMS)

  use Cms\Classes\Theme;
  function onStart()
  {
        $items     = [ ];
        // media dir
        $files     = File::allFiles( 'storage/app/media/gallery/' );
        // OR from theme dir
        // $theme_dir = Theme::getActiveTheme()->getDirName();
        // $files     = File::allFiles( themes_path( $theme_dir ) . '/assets/images/gallery/' );

        foreach ($files as $item) {
            $items[] = $item->getFilename();
        }

        rsort($items, SORT_NUMERIC); // Bigest file number first
        // $items = array_slice($items,0,20); // if you want a limit

        $this['gallery'] = $items;
        //dd( $items );
  }

  <h2>Gallery</h2>

    <div class="showcase-list">
        <div class="row">   
            {% for image in gallery %}
            <div class="col-xs-6 col-sm-3">
                <img src="{{ url('/') }}/storage/app/media/gallery/{{image}}">
            </div>
            {% endfor %}
        </div>
    </div>

A little easier when you dont need a plugin, for something simple.

Let me know if anything could improve here, as still learning the syntax.
