How to retrieve joomla article values, e.g. image_intro - php

Question

I am struggling to retrieve the intro image of articles, within a custom module that echoes article titles with the selected tags.
But it seems as if $item->images doesn't recall the image info. My code is the following:
Can anyone help me?
<?php
defined('_JEXEC') or die;
$images = json_decode($item->images);
?>
<?php JLoader::register('TagsHelperRoute', JPATH_BASE . '/components/com_tags/helpers/route.php'); ?>
<div class="tagsselected<?php echo $moduleclass_sfx; ?>">
<?php if ($list) : ?>
<ul>
<?php foreach ($list as $i => $item) : ?>
<li>
<?php $item->route = new JHelperRoute; ?>
<a href="<?php echo JRoute::_(TagsHelperRoute::getItemRoute($item->content_item_id, $item->core_alias, $item->core_catid, $item->core_language, $item->type_alias, $item->router)); ?>">
<?php if (!empty($item->core_title)) :
echo htmlspecialchars($item->core_title);
endif; ?>
</a>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php else : ?>
<span><?php echo JText::_('MOD_TAGS_SIMILAR_NO_MATCHING_TAGS'); ?></span>
<?php endif; ?>
</div>

Answer 1

Try to get Article images in for loop
<?php foreach ($list as $i => $item) :
// images for each article
$images = json_decode($item->images); ?>
<li>
// your code/ other stuff
// display image
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
</li>
<?php endforeach; ?>

<li class="tag_title_custom">
<?php $item->route = new JHelperRoute; ?>
<a href="<?php echo JRoute::_(TagsHelperRoute::getItemRoute($item->content_item_id, $item->core_alias, $item->core_catid, $item->core_language, $item->type_alias, $item->router)); ?>">
<?php if (!empty($item->core_title)) :
echo htmlspecialchars($item->core_title);
endif; ?>
<?php $images = json_decode($item->core_images);?>
<img src="<?php echo htmlspecialchars($images->image_intro);?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>">
</a>
</li>
