如何阻止第一个帖子调整大小？理想情况下，无论后期订单如何，所有图像都应为590像素宽。
在我看来，这段代码与它有关，但无论我将宽度更改为什么，问题仍然存在。
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 590, 275, true ); // 590 pixels wide by 275 pixels tall, hard crop mode
add_image_size( 'following-post-thumbnails', 250, 200, true ); // 250 pixels wide by 200 pixels tall, hard crop mode

答案 0 :(得分：0)
您应该删除此行，它用于定义自定义缩略图大小：
add_image_size( 'following-post-thumbnails', 250, 200, true ); // 250 pixels wide by 200 pixels tall, hard crop mode
然后更改index.php中的以下行（它告诉缩略图使用上面定义的自定义图像大小）：
<?php the_post_thumbnail('following-post-thumbnails'); ?>
对此：
<?php the_post_thumbnail(); ?>
这应该会导致缩略图使用此行指定的默认大小：
set_post_thumbnail_size( 590, 275, true );
我不确定Wordpress的缩略图是如何工作的，但尝试上传新图片以查看缩略图是否正确调整大小。看起来后续帖子的缩略图会被永久裁剪，并且不会通过更改代码来调整大小。
如果这不起作用，希望此处的文档可以提供帮助：http://codex.wordpress.org/Function_Reference/the_post_thumbnail
