I want to basically show them all. At the moment, it maxes out at 20

This is hardcoded and would require a plugin to change.

Which PHP file is it? Can't I just update it, and manage the maintenance of that change over time? I can just reapply the static change each time I upgrade, probably less time overall than building a plugin.

 

 

For anyone else:

gallery\modules\front\gallery\browse.php line 165

        $featured    = iterator_to_array( \IPS\gallery\Image::featured( 20, NULL ) );
