Magento 2 Cached Image Error – Warning: getimagesize()

If your block extends Magento\Catalog\Block\Product\AbstractProduct, you can use:

$imageType = 'category_page_list'; // choose which image
$image = $block->getImage($product, $imageType);

Then either get the image URL with

$image->getImageUrl();

or if you want to output it as <img> element:

echo $image->toHtml();

If your block does not / cannot extend the abstract product block, you can create a getImage() method on your own:

public function getImage($product, $imageId)
{
    return $this->imageBuilder->setProduct($product)
        ->setImageId($imageId)
        ->create();
}

$this->imageBuilder has to be injected as Magento\Catalog\Block\Product\ImageBuilder

The $imageType or $imageId variables should be one of the image types defined in the theme, for example category_page_list.

See app/design/frontend/Magento/luma/etc/view.xml for all image types in the Luma theme, for example.

In Magento 2 these image types are used instead of defining width and height directly in the template.

Someone solve this with permission 644 files and 755 on folders

Others rename their .htacess file to .htacess-old and checked if the problem persist
