I need to show all the images found under "/themes/theme_name/assets/images/subfolder/*". I thought maybe I could use the glob function in the code section of my page to load images:

function onStart()
{
    $this['files'] = glob('{{ 'assets/images/subfolder/'|theme }}/*.{jpeg,gif,png}', GLOB_BRACE);
}

But this syntax was not accepted. How can I achieve my goal?

Try $this['files'] = glob(themes_path('assets/images/subfolder//*.{jpeg,gif,png}'), GLOB_BRACE);

You can't use twig braces {{}} inside the php header.

Are you sure "themes_path" works correctly? Where has this function been documented?

https://octobercms.com/docs/services/helpers

Unfortunately, there is only the name of the function in that page and no description for that (click on the themes_path link, and nothing happens).

$this['files'] = glob(themes_path('assets/images/subfolder//*.{jpeg,gif,png}'), GLOB_BRACE); returns an empty array apparently. I also tried

$this['files'] = scandir(themes_path('assets/images/subfolder'));

The above line is producing the following exception:

scandir(E:\www\mywebsite/themes/assets/images/subfolder,E:\www\mywebsite/themes/assets/images/subfolder): The system cannot find the path specified. (code: 3)

As you can see, the problem is that the theme_name directory, has not been included in the path. What's wrong with my code?

Huh, you're right. Alright then, I cobbled this together and verified it works. Hope you get good mileage out of it:

    public function onStart()
    {
        $items     = [ ];
        $theme_dir = Theme::getActiveTheme()->getDirName();
        $files     = File::allFiles( themes_path( $theme_dir ) );
        foreach (glob( themes_path( $theme_dir ) . '/*.{yaml,png}', GLOB_BRACE ) as $item) {
            $items[] = url( str_replace( themes_path(), '', $item ) );
        }
        dd( $items );
    }

Thank you buddy. With tiny modifications like adding

use Cms\Classes\Theme;

I wanted to do something similar. These posts helped, thanks! I also wrote up a quick post about iterating over a folder and showing all images therein if anyone needs something similar.
