Steps to Add Product Name as Default Alt Text to All Product Images in Magento 2

Hello Magento Friends,

Today I will be explaining How to Set Product Name as Default Alt Text to All Product Images in Magento 2.

Alt text for product images informs the search engine what the image is about and helps index the product image when the user fires a query related to it. For Magento 2 stores, it is essential to give alt text to all the product images to aid in search engine rankings. Large stores can take advantage of Magento 2 Image Alt Tags Extension to automate the product image alternate text process and save time.

You can also set the product name as the default alt text for all the product images in Magento 2. To do that, follow the below-given steps

Steps to Set Product Name as Default Alt Text to All Product Images in Magento 2:

Step 1: First, we need to create a “di.xml” file inside our extension at the following path

app\code\Vendor\Extension\etc\frontend

Then add the code as follows

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Block\Product\View\Gallery">
	<plugin name="alt_text_plugin" type="Vendor\Extension\Block\Product\View\Gallery\Plugin" sortOrder="10" />
    </type>
</config>

<?xml version="1.0"?>

</type>

</config>

Step 2: After that, we need to create a “ Plugin .php” file inside extension Controller directory

app\code\Vendor\Extension\Block\Product\View\Gallery\

Now add the code as mentioned below

<?php
namespace Vendor\Extension\Block\Product\View\Gallery;

use Vendor\Extension\Helper\Data;
use Magento\Catalog\Model\Layer\Resolver;
class Plugin
{       
    public function afterGetGalleryImages($block, $images)
    {
        try
        {
            $product = $block->getProduct();
            $name=$product->getName();

            foreach ($images as $image) {
                    $image->setLabel($name);
            }
        }
        catch (Exception $e)
        {
            \Magento\Framework\App\ObjectManager::getInstance()->get('Psr\Log\LoggerInterface')->info($e->getMessage());
        }              
        return $images;
    }
}

<?php

namespace Vendor\Extension\Block\Product\View\Gallery;

use Vendor\Extension\Helper\Data;

use Magento\Catalog\Model\Layer\Resolver;

class Plugin

{

public function afterGetGalleryImages($block, $images)

{

try

{

$product = $block->getProduct();

$name=$product->getName();

foreach ($images as $image) {

$image->setLabel($name);

}

catch (Exception $e)

{

\Magento\Framework\App\ObjectManager::getInstance()->get('Psr\Log\LoggerInterface')->info($e->getMessage());

}

return $images;

}

Hi, Thanks for posting the solution; we have implemented the same code by following your instructions, but it has not generated alt text for product images. The product list shows an empty alt, and on the product page, the alt is not showing at all. Any advice on what might be the issue?
Thanks

  Confirm you created the required file for the extension and that the extension is enabled.
  Also, confirm that any other extension does not overwrite the same file.
