Change banner image via Central

Hello, I created a simple HTML page with a banner, I would like to know how I can create an administration area to change the image of this banner.

Banner code:

<div class="slider-style-1">
    <div class="item">
        <div class="overflow-img-banner">
            <img src="assets/img/banner.jpg" class="c-img-banner">
        </div>
    </div>
</div>
