[woocommerce]woocommerce 3.0 product image gallery

woocommerce 3.0升級上去後，在product image gallery這邊有了非常大的變化。

2.6以前在"設定"->"商品"選項裡可以選擇的燈箱效果拿掉了，
導致商品頁的lightbox等效果通通失效。

主要是因為3.0後，woocommerce採取更多樣化的選擇提供給使用者去選擇更多的功能。

詳細資訊可看
https://woocommerce.com/2017/04/woocommerce-3-0-release/

目前解決方式如下

在主題的function.php裡面增加下列程式碼

add_action( 'after_setup_theme', 'yourtheme_setup' );

function yourtheme_setup() {
add_theme_support( 'wc-product-gallery-zoom' );
add_theme_support( 'wc-product-gallery-lightbox' );
add_theme_support( 'wc-product-gallery-slider' );
}

回到前台商品頁
功能有出來了但是css的部分能然要設定一下
