Wordpress调整大小图像并在帖子中显示为拇指

Question

I have set crop in functions.php to resize Images for Posts.

Codex from Wordpress: add_image_size, post_thumbnail

  add_theme_support('post-thumbnails');
  set_post_thumbnail_size(100, 100, true); //size of thumbs
  add_image_size( 'post-thumb', 180, 180, true ); //(cropped)

Usage is like below

<?php if ( has_post_thumbnail() ) { the_post_thumbnail( 'post-thumb' ); } ?>

But it will not resize the thumb and shows the original size. What am I doing wrong?

Wordpress will only resize images on upload, you can use this plugin to resize images on the fly, so the first time you call an image size that does not exists, this plugin will resize the image so the next times image size will exist.
