We’ll demonstrate how to add product image in WooCommerce programmatically and how to get product image in WooCommerce so that you can boost your sales!

WooCommerce B2B  offers two primary methods for including photos with products:

1. Add an Image through WooCommerce Dashboard
2. Add an Image WooCommerce Programmatically

Let’s plunge deep into both approaches.

Adding An Image For A Product In WooCommerce 

We will start with the approach that is to add an image through the WooCommerce dashboard.

• Adding Images To Your Store Through WooCommerce Dashboard

On a WooCommerce store, adding a picture to a product is a rather easy process. The picture meta fields can be found on the sidebar while creating or editing a product.

1. Adding product images and galleries are options available on the right-hand side when adding or editing a product in your store from WooCommerce > Products.
   
2. There, you can display your things with a prominent image and an image gallery with several different images.
3. Any of these will open a modal when you click it, allowing you to upload fresh image files or select an existing one from the WordPress media library.

When uploading photographs to the product gallery, 

1. CTRL + left click, you can pick multiple images and add them all at once.

You can also use pictures from the product’s content description.

If you want to employ this technique, bear in mind that your decision may have an impact on the entire product page’s design. As a result, before adding any photos to the text editor, make sure they are the proper size and alignment.

You see, it is really very simple to add images of the products to your WooCommerce store from the dashboard. However, we have already mentioned that there are two ways to add images on WooCommerce.

 If you want to roll your sleeves up and setup a WooCommerce Store from   Scratch, there’s a step-by-step guide on how to setup WooCommerce store.

The other way is to add images to WooCommerce programmatically if you know how to code, which provides you greater freedom. Let’s have a look at this one, Shall we!

• Adding An Image WooCommerce Programmatically

You might occasionally need to programmatically add images. More options are available to you thanks to this, including galleries, single-product photos, feature shots, and more.

We’ll provide some sample scripts in this area to assist you to add photos to particular products. Keep in mind that you must change the item and picture IDs on the function’s first two lines with your own. You will see an error if the specified item and picture ID don’t exist.

Additionally, remember that now the scripts will only function for one run. This implies that after using them, you can erase them.

The last step is to insert the scripts into your child theme’s functions.php file. 

Go to Appearance > Theme Editor. 

Find the functions.php file in the right column, then paste the code there as described under the next heading below. A plugin like Code Snippets is an alternative.

Note: Please, it is advisable that you make a backup of your website as you will be editing certain fundamental files. 

• Add A Featuring Image To One Product

1. Specify the image ID and product ID as shown below. 

For instance, to set the image with ID 69 as the featured image of the product with ID 198.

function QuadLayers_add_featured_image() {
    $imageID = 69; // Image ID
    $post_id = 198; //Product ID
    set_post_thumbnail( $post_id, $imageID );
}
add_action('init', 'QuadLayers_add_featured_image');

Every time a page loads, the function may be performed everywhere thanks to the init hook. Additionally, we set the featured picture using the set post thumbnail() function. Both posts and products can use this.

• Add A featuring Image To More Than One Product

Now to add a featured image to multiple products you need to repeat the same process. 

1. Specify the image ID and product IDs (of products you are adding the image to) as shown below. 

The following script shows script will add the image with ID 52 to products with IDs 36, 37, and 38.

function QuadLayers_multiple_featured_image() {
    $imageID = 52; // Image ID
    $post_id = array(36,37,38); //Product IDs
    for ($ii=0; $ii < count($post_id); $ii++) { 
           set_post_thumbnail( $post_id[$ii], $imageID );      
    }
}
add_action('init', 'QuadLayers_multiple_featured_image');

As you can see, we’ve added all of the product IDs to an array while keeping the script otherwise unchanged. You can do this to simultaneously allocate the very same featured image to multiple goods.

This may be advantageous for product modifications that don’t result in cosmetic adjustments. Use the same featured image, for instance, for versions of the very same mobile phone but various RAM sizes.

• Add images To Item Gallery 

Adding an image to a product gallery in WooCommerce is slightly more complex because you need to use two functions. 

1. The mentioned script prepares the data for the function (QuadLayers_create_gallery) required for creating create the gallery. ( list of images and the product ID where you wanted to be added to the gallery)
2. The update_post_met() creates the gallery. To create this, you are required to utilize the ID of the product for adding to the gallery and a list of images in an array.

function QuadLayers_create_gallery(){ 
        $imgs_ids=array(48,53,47); //image IDs
        add_img_to_gallery(195,$imgs_ids); // product id
}
function add_img_to_gallery($product_id,$image_id_array){
        update_post_meta($product_id, '_product_image_gallery', implode(',',$image_id_array));
}
add_action('init','QuadLayers_create_gallery');

• Setting A Default Image To Products 

We’ve seen that to set the featured image of a product.

1. 1. Go to the admin dashboard, WooCommerce > Settings > Products. To add an image ID, navigate to the Media -> Library, click on the desired image, and copy the ID from the URL. For example, if the URL ends with item=12345, then 12345 is your image ID.

2. To set a default image WooCommerce programmatically, use the         snippet mentioned below.

function my_custom_woocommerce_placeholder( $image_url ) { $placeholder_image_id = 123; // Replace with your placeholder image ID $image_url = wp_get_attachment_url( $placeholder_image_id ); return $image_url; } add_filter( 'woocommerce_placeholder_img_src', 'my_custom_woocommerce_placeholder' );

All the products lacking featured images will thereafter receive a default image. Remember to change it with the appropriate path to your image since you will use the image path here rather than an ID.

Advanced Image Management in WordPress

Managing images in WordPress effectively is essential for optimizing your site’s performance and ensuring a consistent visual experience. In this guide, we’ll explore how to add custom image sizes and remove default image sizes in WordPress by editing your theme’s functions.php file.

Adding Custom Image Sizes

To create custom image sizes, you’ll need to modify your theme’s functions.php file. Custom image sizes allow you to control the dimensions of images used on your site, ensuring they fit perfectly into your design.

Step 1: Open Your functions.php File

• Locate your theme’s functions.php file. You can find this in your WordPress dashboard by navigating to Appearance > Theme Editor and selecting functions.php from the list of files.

Step 2: Add the Custom Image Size Code

• Add the following code to define a new custom image size:
