How to get Magento 2 product image on custom phtml by product id Without loading product collection

Question

I need product image on custom phtml in magento 2.

Product is collection is a array not object.

I just want to product product_base_image , without loading product collection.

I tried

<?php

namespace Dev\Core\Helper;

use Magento\Catalog\Helper\Image;
use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\App\Helper\Context;

class Cart extends \Magento\Framework\Url\Helper\Data {

    public function __construct(
    Context $context, StoreManagerInterface $storeManger, ProductRepositoryInterface $productRepository, FormKey $formKey, Image $imageHelper
    ) {

        $this->imageHelper = $imageHelper;
        $this->productRepository = $productRepository;

        parent::__construct($context);
    }



    public function getItemImage($productId) {
        try {
            $_product = $this->productRepository->getById($productId);
        } catch (NoSuchEntityException $e) {
            return 'product not found';
        }
        $image_url = $this->imageHelper->init($_product, 'product_base_image')->getUrl();
        return $image_url;
    }

}

I m getting image with no issue. But i want to load image by product id without loading collection.

You can get the images directly, without loading the entire product, by using the following query:

<?php
namespace Dev\Core\Helper;

use Magento\Framework\App\Helper\Context;
use Magento\Framework\App\ResourceConnection;

class Cart extends \Magento\Framework\App\Helper\AbstractHelper
{
    private $_connection;

    public function __construct(
        Context $context,
        ResourceConnection $resourceConnection
    ) 
    {
        $this->_connection = $resourceConnection->getConnection();

        parent::__construct($context);
    }

    public function getItemImage($productId) 
    {
        $select = $connection->select()
            ->from('catalog_product_entity_media_gallery_value', '*')
            ->join(
                'catalog_product_entity_media_gallery',
                'catalog_product_entity_media_gallery_value.value_id=catalog_product_entity_media_gallery.value_id',
                array('image' => 'value')
            )
            ->where('entity_id = ?', $productId);

        try 
        {
            return $this->_connection->fetchAll($select);
        } catch (Exception $e) 
        {
            //log or handle exception
        }
    }
}
