    Hi.
    I have NO problem with the template. I just wanted to ask for a advise.
    I am using Copius pro template.
    Is there a way to replace all missing images with one that would be a default?
    I am talking about the blog view. Let’s say that intro image or full image from an article gets deleted (or doesn’t exist).It would be great if it could be replaced by a default one.
    I hope you understand my english.
    Thank you
    Elias

    Okay, in the next release, we will add the option look like this

    Dummy Img

    You can see the default img added if intro image or full image are not added via Joomla article.

    Do you need the particle now or wait for the next release?

    Or just replace the code for joomlacontent.html.twig like so

    {% extends '@nucleus/partials/particle.html.twig' %}

{% block stylesheets %}
  <link rel="stylesheet" href="{{ url('gantry-theme://css/uikit.min.css') }}" type="text/css" />
  <link rel="stylesheet" href="{{ url('gantry-theme://css/components/slider.min.css') }}" type="text/css" />
  <link rel="stylesheet" href="{{ url('gantry-theme://css/components/dotnav.min.css') }}" type="text/css" />
  <link rel="stylesheet" href="{{ url('gantry-theme://css/components/slidenav.min.css') }}" type="text/css" />
{% endblock %}

{% block javascript_footer %}
  {% do gantry.load("jquery") %}
  <script src="{{ url('gantry-theme://js/uikit.min.js') }}"></script>
  <script src="{{ url('gantry-theme://js/components/slider.min.js') }}"></script>
  <script src="{{ url('gantry-theme://js/components/slideset.min.js') }}"></script>
  <script src="{{ url('gantry-theme://js/components/lightbox.min.js') }}"></script>
{% endblock %}

    Tony thank you so much.
    But as I said my english are poor so perhaps you misunderstood me (I am using translator 🙂

    I was talking about blog view from the template . I am not using particle to display the blog pages. Do you think that I should start using the content particle in my blog pages? (Categories view)

    There is a html folder in the template folder. It has a subfolder com content….
    I hope that you understand now what I am trying to do.

    Again this is not a problem. I will understand if you can’t help becouse it’s out from support.
    If you find some time please give me your advise.
    Thaaaaaaank you!!!!!!!!

    Hi Elias,

    I understand your question. IMO, this case related to override the joomla com_content, Please take a look this https://docs.joomla.org/Layout_Overrides_in_Joomla and this https://docs.joomla.org/How_to_override_the_output_from_the_Joomla!_core

    Have a nice day
