In my custom block, I get Product Collection use MagentoCatalogModelResourceModelProductCollectionFactory, when I output one product in it, the image, thumbnail, small_image are the same url like below, a large image(1380px x 1340px) url：

[image] => /m/b/mb04-black-0.jpg

[small_image] => /m/b/mb04-black-0.jpg

[thumbnail] => /m/b/mb04-black-0.jpg

Did I do something wrong? How do I get the real small_image or thumbnail URL from product collection?

More question description

For example, in the default luma theme category, product list always get the image like below:

<img class="product-image-photo" src="http://local.com/pub/media/catalog/product/cache/small_image/240x300/beff4985b56e3afdbeabfc89641a4582/w/t/wt09-white_main.jpg" width="240" height="300" alt="Breathe-Easy Tank">

How can I get that?

My code example

Below is my code, I remove some function for simplicity.

<?php

namespace VendorTemplateBlock;



use MagentoFrameworkViewElementTemplate;

use MagentoBackendBlockTemplateContext;

use MagentoCatalogModelResourceModelProductCollectionFactory;



class Product extends Template

{

    protected $_productCollectionFactory;



    public function __construct(

        Context $context,

        CollectionFactory $productCollectionFactory,

        array $data = 

    )

    {

        $this->_productCollectionFactory = $productCollectionFactory;

        parent::__construct($context, $data);

    }



    public function getProductCollection()

    {

        $skus = $this->getData('products_count');

        $collection = $this->_productCollectionFactory->create();

        $collection->addAttributeToSelect('*')

            ->addAttributeToFilter(

                'sku', array('in' => $skus)

            );

        return $collection;

    }

}

Then you should use `MagentoCatalogHelperImage ' resize the product image

$resizedImage = $this->_productImageHelper->init($product, 'product_small_image')

                                           ->constrainOnly(TRUE)

                                           ->keepAspectRatio(TRUE)

                                           ->keepTransparency(TRUE)

                                           ->keepFrame(FALSE)

                                           ->resize(200, 300);
