Netizen footer store name change to png logo or different text

Question

I would like to change the left footer store name text on my big cartel site which is the theme netizen.

I think I need to change this code but not sure how to replace it with a logo or different text.

      <div class="footer-section footer-store-name">
    {{ store.name }}
  </div>

I am not sure what to do here
