如果您使用任何woocommerce兼容模板，那么你会在模板文件夹中找到一个名为woocommerce的目录。

If you use any woocommerce compatible template then you'll find a directory named "woocommerce" in your template folder.

如果您找不到，则会是 wp-contents / plugins / woocommerce / templates 目录。在这种情况下，您的主题不会覆盖默认布局。然后你需要找到模板（或woocommerce）/single-product/product-image.php 文件。在第21行你应该找到如下 -

If you can't find it then it'll be the wp-contents/plugins/woocommerce/templates directory. In that case your theme doesn't overwrite the default layout. Then you need to find templates(or woocommerce)/single-product/product-image.php file. Around line 21 you should find something as following-

$image_title = esc_attr( get_the_title( get_post_thumbnail_id() ) );

在该行添加// infront（注释掉），如下 - 。

add // infront of that line (comment that out) as follows-.

// $image_title = esc_attr( get_the_title( get_post_thumbnail_id() ) );

现在搜索 rel =prettyPhoto在中删除 rel =prettyPhoto的 title =％s

在上一个文件夹中再次找到 product-thumbnailails.php 。在40左右，你会看到如下的一些东西 -

Again find product-thumbnails.php in the same folder of the previous one. In around 40 you'll see something as follows like before-

$image_title = esc_attr( get_the_title( $attachment_id ) );

注释，添加两个正斜杠（//）就像上一个。
现在再次在第42行搜索 prettyPhoto [product-gallery] ，当你找到 title =％s 附近，并像之前一样删除。

Comment this out adding two forward slashes(//) just like the previous one. Now again in around line 42 search for something prettyPhoto[product-gallery] and when you find it look for title="%s" nearby and remove it like before.

这会移除灯箱图片查看器中的标题。

This will remove the title form the lightbox picture viewer.

这下面的脚本在你的header.php文件或任何你可能找到合适 -

Instead of all these works you can simply use this following script inside your header.php file or anywhere you may find suitable-

<script>
    jQuery(document).ready(function(){
        jQuery('a[rel*="prettyPhoto"]').attr('title','').find('img').attr('alt','');
    });
</script>
