I'm trying to add the tag , loading="lazy" to the template that I've found that prints the image, but it´s not working.


<span class="product-image-container" data-bind="style: {width: width + 'px'}">
    <span class="product-image-wrapper"  data-bind="style: {'padding-bottom': height/width*100 + '%'}">
        <img class="product-image-photo" data-bind="attr: {src: src, alt: alt, 'loading': 'lazy'}" />

It's not changing anything. Now I've found that list.phtml template prints the image like this

 $productImage = $block->getImage($_product, $image);
<?php echo $productImage->toHtml() ?>

But this is a block as far as I know, I just don't know where to find that .phtml block, or is it the one that I'm modifying?

I don't think there is any reason to pass this in as a data-bind attribute, since this is a static value. Try adding it as a regular HTML attribute?

<img class="product-image-photo" loading="lazy" data-bind="attr: {src: src, alt: alt}" />
  • did not work either, even my <h1>Test</h1> is not visible Commented Mar 2, 2022 at 18:29
  • oh my bad, I've found that the actual template is this Magento_Catalog::product/image_with_borders.phtml, it's found on ImageFactory Commented Mar 2, 2022 at 20:55

I've found the right template, it's here: Magento_Catalog::product/image_with_borders.phtml

You can find it here Magento\Catalog\Block\Product\ImageFactory

on create method:

$data = [
            'data' => [
                'template' => 'Magento_Catalog::product/image_with_borders.phtml',
                'image_url' => $imageAsset->getUrl(),
                'width' => $imageMiscParams['image_width'],
                'height' => $imageMiscParams['image_height'],
                'label' => $this->getLabel($product, $imageMiscParams['image_type']),
                'ratio' => $this->getRatio($imageMiscParams['image_width'], $imageMiscParams['image_height']),
                'custom_attributes' => $this->getStringCustomAttributes($attributes),
                'class' => $this->getClass($attributes),
                'product_id' => $product->getId()
