Magento 1.9 Cart Images Not Displaying – How to Resolve

I figured it out. I turned on template path hints to see exactly which file was being used to render the new products widget on the home page. It showed this path:

/app/design/frontend/base/default/template/catalog/product/new.phtml

The code to get the image was hard-coded to resize to 135!:

<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->escapeHtml($_product->getName()) ?>" class="product-image"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(135) ?>" width="135" height="135" alt="<?php echo $this->escapeHtml($_product->getName()) ?>" /></a>

I know I should not edit this file directly, so I copied it into the following path (for the rwd theme, which is what I am using):

app/design/frontend/rwd/default/template/catalog/product/new.phtml

And then replaced that code with this code:

<?php $_imgSize=300; ?>
<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->escapeHtml($_product->getName()) ?>" class="product-image"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize($_imgSize) ?>" width="<?php echo $_imgSize ?>" height="<?php echo $_imgSize ?>" alt="<?php echo $this->escapeHtml($_product->getName()) ?>" /></a>

Hopefully, this will help other people, too. It had me stumped for quite a while.

Inside Block file keep below code,

   protected $_filesystem ;
   protected $_imageFactory;
   public function __construct(            
        \Magento\Framework\Filesystem $filesystem,         
        \Magento\Framework\Image\AdapterFactory $imageFactory         
        ) {         
        $this->_filesystem = $filesystem;               
        $this->_imageFactory = $imageFactory;         
        }

    // pass imagename, width and height
    public function resize($image, $width = null, $height = null)
    {
        $absolutePath = $this->_filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA)->getAbsolutePath('custom_module/posts/').$image;
        if (!file_exists($absolutePath)) return false;
        $imageResized = $this->_filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA)->getAbsolutePath('resized/'.$width.'/').$image;
        if (!file_exists($imageResized)) { // Only resize image if not already exists.
            //create image factory...
            $imageResize = $this->_imageFactory->create();         
            $imageResize->open($absolutePath);
            $imageResize->constrainOnly(TRUE);         
            $imageResize->keepTransparency(TRUE);         
            $imageResize->keepFrame(FALSE);         
            $imageResize->keepAspectRatio(TRUE);         
            $imageResize->resize($width,$height);  
            //destination folder                
            $destination = $imageResized ;    
            //save image      
            $imageResize->save($destination);         
        } 
        $resizedURL = $this->_storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA).'resized/'.$width.'/'.$image;
        return $resizedURL;
  } 

Now Call inside phtml file,

$block->resize('test.jpg',500,400);
