How do I add an image picker?

Easy! In your theme’s functions.php file, add the following code:

function register_custom_image_pickers() {
    add_theme_support('mfi-reloaded', array(
        'hero-image' => array(
            'post_types' => array('post'),
            'labels' => array(
                'name' => __('Hero Image'),
                'set' => __('Set hero image'),
                'remove' => __('Remove hero image'),
                'popup_title' => __('Set Hero Image'),
                'popup_select' => __('Set hero image'),
            ),
        ),
        'sidekick-image' => array(
            'post_types' => array('post'),
            'labels' => array(
                'name' => __('Sidekick Image'),
                'set' => __('Set sidekick image'),
                'remove' => __('Remove sidekick image'),
                'popup_title' => __('Set Sidekick Image'),
                'popup_select' => __('Set sidekick image'),
            ),
        ),
    ));
}
add_action('after_setup_theme', 'register_custom_image_pickers');
