将类属性附加到woocommerce单个产品图像

- $image_title= esc_attr( get_the_title( get_post_thumbnail_id() ) ); $image_link= wp_get_attachment_url( get_post_thumbnail_id() ); $image= get_the_post_thumbnail( $post-> ID, apply_filters( 'single_product_large_thumbnail_size', 'shop_single' ), array( 'title' => $image_title ) ); $attachment_count= count( $product-> get_gallery_attachment_ids() ); if ( $attachment_count > 0 ) { $gallery = '[product-gallery]'; } else { $gallery = ''; }echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '< a href="http://www.srcmini.com/%s" itemprop="image" class="woocommerce-main-image zoom" title="%s"rel="prettyPhoto' . $gallery . '"> %s< /a> ', $image_link, $image_title, $image ), $post-> ID );

【将类属性附加到woocommerce单个产品图像】上面是woocommerce的product-image.php文件中的代码。我想为单个产品的图像添加一个类。我无法找到解决方法。请帮忙。
谢谢

$image = get_the_post_thumbnail( $post-> ID, apply_filters( 'single_product_large_thumbnail_size', 'shop_single' ), array( 'title' => $image_title, 'class' => 'your class here' ));

我在get_the_post_thumbnail中添加了类密钥
