## 描述

Thumbnail Updater does exactly what it’s name implies: it updates thumbnails. WordPress
2.9 introduced support for
 post thumbnails but one problem is that the support 
is not backwards compatible—meaning that if you downloaded or created a theme that
supports post thumbnails, any images uploaded prior to the activation of that theme
will not have the new thumbnail size.

## 安装

Installation is easy. Unzip into your wp-content/plugins directory and activate.
Thumbnail Updater can be accessed through the Media Library. Navigate to Media Library,
click on any image and you should a button that says “Update Image Sizes.” Clicking
on that will open a popup that lists all of the available image sizes. If a thumbnail
size exists for that image, there will be a check next it. If the thumbnail size
doesn’t exist, then a red exclamation mark will appear.

 1. Upload the `thumbnail-update` folder to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress

That’s all!

## 常见问题

  Hey! Your plugin keeps saying Error! What’s wrong?

Possibly permission problems. If you’re like me, you probably have a two-year-old
blog and have switched hosts at least three times
 in that last year. What does 
that have to do with permissions? Well, some of your older uploads—those dating 
prior to your last webhost change—either A) don’t have the folders and files set
to 777 and 666 (respectively) or B) Owner:group isn’t set to www-data:www-data. 
The first problem is relatively easy to deal with using any good FTP program. The
second problem requires that your web-host allows shell-access to their servers.
If not, you’ll have to contact them to get the groups changed. Finally, I’ve run
into some issues with the oldest files on my server. It didn’t matter if I changed
permissions or owners on the directory or files, I still could not get thumbnails
to generate.
