[Arisandi, Donny (ICRAF)]

Hi Paolo, that I was looking for. But in template, how to get the the URL and Image for the map? I tried like below script it did not work. Please advise.

<h4 class="subheading">{% trans "Recent Map" %}</h4>
      {% for content in recent_maps %}
        <div class="col-md-3">
          <div class="recent-box">
            <div class="text-center">
              <a href="{{ map.detail_url }}" title="{{ map.name|escape }}">
                <img src="{{ map.thumbnail_url }}" alt="thumbnail" width="250" height="150">
                <div class="recent-abstract">
                  {{ content.abstract|escape|urlize|linebreaks|safe|truncatechars:250 }}
                </div>
                <div class="recent-title">{{ content.title|escape|truncatechars:30 }}</div>
              </a>
            </div>
          </div>

I think Donny would like to see thumbnails of recently update maps.

If this is the case, this can be easily done with:
Map.objects.all().order_by('-last_modified') in the views.py.
Then use map.get_thumbnail_url in the template
