Hi there,

Thanks for contacting us. Sorry for the inconvenience. The sidebar is not dynamic. If you want to put an banner image there you need add code.

templates/shaper_shopin/html/com_j2store/templates/bootstrap3/default_filters.php

Add this code after line on 173

You need to change image name

<?php if(count($this->filters['manufacturers'])): ?>
        <!-- Brand / Manufacturer Filters -->
        <div class="j2store-product-filters manufacturer-filters">

        <div class="j2store-product-filter-title j2store-product-brand-title">

        </div>
            <div id="j2store-brand-filter-container" class="control-group"  >
               <a href="#"><img src="/images/logo.png" alt=""></a>
            </div>
        </div>
    <?php endif;?>
