Get product Image from Review Collection

[silici0]

I have a ReviewCollection, im trying to each "Review/Product" get a product image so i can pass on and display on template file:

public function getCollection()
    {
//\Magento\Review\Model\ResourceModel\Review\Product\CollectionFactory $_reviewsColFactory,
        $collection = $this->_reviewsColFactory->create()->addStoreFilter(
                $this->_storeManager->getStore()->getId()
            )->addStatusFilter(
                \Magento\Review\Model\Review::STATUS_APPROVED
            )->setDateOrder();

        $arr = array();
        foreach ($collection as $_review) {
            $days = $this->returnDays($_review);
            if ($days <= $this->_days) {
                if (!isset($arr[$_review->getSku()])) {
                    $arr[$_review->getSku()]['cont'] = 1;
                } else {
                    $arr[$_review->getSku()]['cont']++;
                }
                $arr[$_review->getSku()]['productUrl'] = $_review->getProductUrl();
                $arr[$_review->getSku()]['productName'] = $_review->getName();
                $arr[$_review->getSku()]['productImg'] = $_review->getImage(); //Empty
            }
        }
        // arsort($arr);
            
        return $collection;
    }

In that case is every $_review a Model/Product ? 

Thanks

You can get item image based on sku from review collection,

just add dependency on __construct() method,

 public function __construct(
     \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
 ) {
     $this->productRepository = $productRepository;       
 }                     
try {
     $itemSku = $_review->getSku();     
     $productData = $this->productRepository->get($itemSku);
     $itemImage = $productData->getData('image');
 } catch (\Exception $exception) {
     $productData = null;
     return "Invalid sku";
 };

Set $itemImage inside your function and you got image name.

Ty for the answer, i found out that from $reviewCollection->getId returns me the productId, loading ProductRepositoryInterface i got the imageUrl as follow: 

$imageBlock =  $this->getLayout()->createBlock('Magento\Catalog\Block\Product\ListProduct');
$productImage = $imageBlock->getImage($product, 'category_page_grid');
$productImage->toHtml();

I uploaded the full code at my GitHub.
