Method 1: Modifying your Theme’s Template Files (Advanced Users)

You’ll need to locate the template file responsible for displaying product thumbnails, often `content-product.php` or a similar file within your theme’s directory. Within this file, you’ll find the code that generates the `` tag. You can then modify the attributes directly. For example, to add alt text:
ID ); $image_alt = get_post_meta( $image_id, '_wp_attachment_image_alt', true ); // Retrieve existing alt text
// Add or modify alt text here. If no alt text exists, set a default.
if(empty($image_alt)){
$image_alt = “Default Alt Text for Product Image”;
}
//Generate image tag with modified alt text. Remember to use appropriate function for getting image URL based on your theme
echo wp_get_attachment_image( $image_id, ‘woocommerce_thumbnail’, false, array(‘alt’ => $image_alt, ‘title’ => ‘Product Title’));
?>
Method 2: Using a WooCommerce Plugin (Recommended for Beginners)
Numerous plugins are available that allow you to easily manage image attributes. These plugins usually provide a user-friendly interface for adding or editing alt text and other attributes without needing to touch code. This is the safest and easiest method for most users. Search the WordPress plugin directory for “WooCommerce image optimization” or “WooCommerce alt text”. Install and activate a reputable plugin to streamline the process.
Method 3: Using a Custom Function and Filter (Intermediate Users)
For more precise control, you can create a custom function and apply it using a filter. This method requires some PHP knowledge. You can use the `woocommerce_get_image` filter to modify the image tag before it’s displayed.
Remember to replace `”Your custom alt text here”` with your desired alt text. You can add other attributes within `$attr` similarly. Place this code within your theme’s `functions.php` file or a custom plugin.
