显示全尺寸图像.
推荐答案
您需要在 functions.php 文件中添加不同的图像大小.WordPress 将在创建新图像时创建这些调整大小的图像.
You need to add different image sizes in your functions.php file. WordPress will then create these resized images when a new image is created.
用法如下:
<?php add_image_size( $name, $width, $height, $crop ); ?>

如果您希望追溯创建这些图像尺寸(针对您已经添加的图像)，那么您需要重新生成缩略图.您可以使用重新生成缩略图插件来执行此操作.
If you wish to create these image sizes retrospectively (to images you've already added) then you'll need to regenerate your thumbnails. You can do this using the regenerate thumbnails plugin.
然后您可以在代码中引用图像大小.一个完整的例子:
You can then reference a image size in your code. A full example:
在functions.php里面:
add_image_size( 'example_size', 200, 200, true );
在您的主题中:
$thumb_url = wp_get_attachment_image_src( $thumb_id, 'example_size', true );
