I have achieved it using below code.
path to file: module-catalog/view/frontend/templates/product/view
edit:attribute.html
This is default Code:
<?php
$_helper = $this->helper('Magento\Catalog\Helper\Output');
$_product = $block->getProduct();
$_call = $block->getAtCall();
$_code = $block->getAtCode();
$_className = $block->getCssClass();
$_attributeLabel = $block->getAtLabel();
$_attributeType = $block->getAtType();
$_attributeAddAttribute = $block->getAddAttribute();
if ($_attributeLabel && $_attributeLabel == 'default') {
$_attributeLabel = $_product->getResource()->getAttribute($_code)->getFrontendLabel();
}
if ($_attributeType && $_attributeType == 'text') {
$_attributeValue = ($_helper->productAttribute($_product, $_product->$_call(), $_code)) ? $_product->getAttributeText($_code) : '';
} else {
$_attributeValue = $_helper->productAttribute($_product, $_product->$_call(), $_code);
}
?>
<?php if ($_attributeValue): ?>
<div class="product attribute <?php /* @escapeNotVerified */ echo $_className?>">
<?php if ($_attributeLabel != 'none'): ?><strong class="type"><?php /* @escapeNotVerified */ echo $_attributeLabel?></strong><?php endif; ?>
<div class="value" <?php /* @escapeNotVerified */ echo $_attributeAddAttribute;?>><?php /* @escapeNotVerified */ echo $_attributeValue;
if($_className=='description')
{
?>
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($_product->getId());
$images = $product->getMediaGalleryImages();
foreach($images as $child){ ?>
<img src="<?php echo $child->getUrl(); ?>" >
<?php } ?>
<?php } ?>
</div>
</div>
<?php endif; ?>
Add after
<div class="value" <?php /* @escapeNotVerified */ echo $_attributeAddAttribute;?>><?php /* @escapeNotVerified */ echo $_attributeValue;
<?php /* @escapeNotVerified */ echo $_attributeValue;
if($_className=='description')
{
?>
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($_product->getId());
$images = $product->getMediaGalleryImages();
foreach($images as $child){ ?>
<img src="<?php echo $child->getUrl(); ?>" >
<?php } ?>
<?php } ?>
You will get a list of product images on product listing page as shown in below image:
