Hi Renzo,

I was able to figure out a way to add captions to my images. Hope this helps.

You'll need to add some code to this file; templates/your_template_name/html/com_content/articles/default.php

Around line 118 (may be different on your template) you'll see this line (had to remove the open and closing php tags, be sure to add them back):

echo LayoutHelper::render('joomla.content.full_image', $this->item); 

Just below it add this:

if ($images->image_fulltext_caption) : echo '<div class="captions"><span class="image-caption">' . htmlspecialchars($images->image_fulltext_caption) . '</span></div>'; endif;

For it to appear you'll need to add your caption in the Full Image caption field under Images and Links of the Joomla article.

I also added the following CSS to style it up a bit:

.article-details .article-full-image {
    text-align: center;
    margin-bottom: 1rem;
}
.captions {
margin-bottom: 20px;
}
span.image-caption {
    border-left: 3px solid #4392f1;
    padding: 0px 0px 0px 8px;
    font-style: italic;
}

P.S. Joomshaper, you should really stop removing core article functionality from Joomla Articles. There should be an ALT field and Caption field under the Blog Option images.

Kind regards, John
