Images Uploaded in CMS not showing on mobile [desktop is fine] Just want uploaded images for entries to show for desktop AND mobile

{% set assets = entry.galleryImage %}

{% if assets | length %}

{% for asset in assets %}
    {% if asset.kind == 'video' %}
        &lt;video class="vid" preload="none" controls="false" loop webkit-playsinline muted&gt;
            &lt;source src="{{ asset.url }}" poster="{{ asset.url }}" type="video/mp4"&gt;
        &lt;/video&gt;
    {% else %}
        &lt;img class="gallery_img_1"  src="{{ asset.url }}"&gt;
    {% endif %}
{% endfor %}
From Craft's POV, there's no difference between desktop and mobile.  I'd check your CSS to see if you're changing how things are displayed depending on the @media query breakpoints.
