Image slider in the page

I have a slider in the index page, which has 3 pictures and this pictures has links. What is the best way to change pictures and links: make db table sliders:

id
pic
link

and work with it, or make in config->settings.php something like this:

<?php
return [
    'new_products_count' => 6,
    'popular_products_count' => 6,
    'paginate' => 20,
    'admin_paginate' => 10,
    'slider'=>[
    1=>['img'=>'1.jpg','link'=>'www1']
    2=>['img'=>'2.jpg','link'=>'www2']
    3=>['img'=>'3.jpg','link'=>'www3']
    ]
]; 

and work with it like this:

Config::set('settings.slider['img']=>'newimg.jpg')
Config::set('settings.slider['link']=>'newWWW')

?
