How to Remove Unused WooCommerce Images from Your Dokan Marketplace

Looking for solutions to remove images while doing bulk delete WooCommerce products?

While running an online business, you must be vigilant. You should be aware of everything like trending fashion, new trends, and the outdated products of your store. You can keep your site updated with the latest products that are more likely to be sold.

In order to keep your store up-to-date, sometimes you need to delete some products that have not been sold for a long time or products that are out of season. For a WooCommerce store, you can easily do this using the default WooCommerce setting or running an SQL command.

But the problem is WordPress does not delete media upon deleting a post. This could be a major issue for an eCommerce site or marketplace having thousand of high-quality images.

In the following blog, you'll learn how to remove WooCommerce images from the gallery when deleting a product for both a single store and multivendor marketplace.

Why You Should Remove WooCommerce Product Images after Deleting That Product

You need to upload plenty of products with thousands of related images for your eCommerce store. And sometimes it's also very normal to delete some products from your site due to some reasons. After deleting a product if you check your media library you will find all those images which were used for your deleted products.

This means that after deleting a product in WooCommerce, the system removes most of the data associated with it. But the image of that product will remain in the database and the media folder. It will make your site unnecessarily heavy.

Benefits of Removing Product Images after Deleting That Product
1. Improve site performance
2. Increase store speed by minimizing server storage
3. Keep the site lightweight
4. Create more space for further uploading
5. Optimize the store database

For marketplace owners, the scenario is a little bit more complex. It's severely difficult to monitor all the media files uploaded by different vendors. Since a vendor possibly uploads a good number of products every day and also deletes many of the existing ones. In turn, their product images may reduce your server space which is not good for your site performance.

In that case, it would be beneficial to delete all the featured image and gallery image if the user/vendor delete any product.

But another problem can arise there if someone uses the same images on multiple posts.

Well, today we'll show you solutions to manage all these obstacles.

        foreach ( $products->posts as $post ) {
            array_push( $all_product_ids, $post->ID );

            array_push( $product_thum_id_holder, get_post_thumbnail_id( $product_id ) );
            $wc_product        = wc_get_product( $product_id );
            $gallery_image_ids = $wc_product->get_gallery_image_ids();
            if ( empty( $gallery_image_ids ) ) {
            foreach ( $gallery_image_ids as $gallery_image_id ) {
                array_push( $gallery_image_id_holder, $gallery_image_id );
    if ( ! in_array( $thum_id, $product_thum_id_holder ) && ! in_array( $thum_id, $gallery_image_id_holder ) ) {
        wp_delete_attachment( $thum_id, true );
        if ( empty( $thum_id ) ) {
        $gallery_image_ids = $product->get_gallery_image_ids();
        if ( empty( $gallery_image_ids ) ) {
        foreach ( $gallery_image_ids as $gallery_image_id ) {
