wordpress - 图像媒体正在创建 768px 的新图像大小，但如何阻止它？

Question

更新到 WordPress 4.5 后，我正在进行媒体上传测试，我注意到我正在生成一个新的图像大小，但我不知道如何停止。

我当前用来防止生成多种尺寸的媒体的函数是:

function add_image_insert_override( $sizes ) {
    unset( $sizes[ 'thumbnail' ]);
    unset( $sizes[ 'medium' ]);
    unset( $sizes[ 'large' ]);
    unset( $sizes[ 'full' ] );
    return $sizes;
}
add_filter( 'intermediate_image_sizes_advanced', 'add_image_insert_override' );

如何阻止 WordPress 4.5 生成宽度为 768px 的图像？

Answer 1

除了我在 Responsive Images in WordPress 4.4 下引用的文章之外，我没有在任何地方找到此内容。当他们指示已创建新的图像尺寸时:

A new default intermediate size, medium_large, has been added to better take advantage of responsive image support. The new size is 768px wide by default, with no height limit, and can be used like any other size available in WordPress. As it is a standard size, it will only be generated when new images are uploaded or sizes are regenerated with third party plugins.

读完这篇文章后，我可以将我的函数更新为:

function add_image_insert_override( $sizes ){
    unset( $sizes[ 'thumbnail' ]);
    unset( $sizes[ 'medium' ]);
    unset( $sizes[ 'medium_large' ] );
    unset( $sizes[ 'large' ]);
    unset( $sizes[ 'full' ] );
    return $sizes;
}
add_filter( 'intermediate_image_sizes_advanced', 'add_image_insert_override' );

现在，当我向帖子添加媒体时，我不再生成 foobar-768xwhatever。希望这对下一个人有帮助。
