<a href="#">
    <img data-fred-attrs="alt" data-fred-name="image_{{i}}"
       src="/assets/components/anybase/uploads/logo.svg"
       alt="YouSite logo"
    />
</a>
{% else %}
<img data-fred-attrs="alt" data-fred-name="image_{{i}}"
    src="/assets/components/anybase/uploads/logo.svg"
    alt="YouSite logo"
