Change image of banner at top of categories

[Ku4rtz]

Hello,

I would like to change this part of code :

I would like in fact to put a static image here not dependant of what category is watched.

I tried to change the file /shopV2/themes/fashion3/templates/catalog/listing/category.tpl.

And I finally found the part of code that I needed :

{block name='product_list_header'}
                 {*
                   {if isset($category) && $category.image.large.url}
                       <div class="bn-top ">
                <div class="container_img_bread has-img ">
                        {include file='_partials/breadcrumb.tpl'}
                        <div class="category-cover">
                          <img src="{$category.image.large.url}" alt="{$category.image.legend}">
                        </div>
                            {else}
                        <div class="container_img_bread no-img ">
                         {hook h="blockPosition8"}
                         {include file='_partials/breadcrumb.tpl'}
                         </div>
                                </div>
                           </div>                        
                    {/if}*}
        {if $category.description}
            <h1 class="category_h1">{$category.name}</h1>
            <div id="category-description" class="text-muted">{$category.description nofilter}</div>
        {/if}
        
{/block}

The problem is that if I change something in this code, nothing happen on the website. Even if I delete the if condition, no change. So I tried to cause a bug with deleting a bracket. And the page couldn't respond so I was on the right file?

Thanks for your help.
