內容簡介
WordPress 主題需要不同尺寸的縮圖，甚至讓用戶更改這些尺寸。
但 WordPress 存在一個問題：在註冊新的尺寸時，它不重新生成縮圖。
縮略圖攔截了主題或插件向 WordPress 請求特定縮略圖的請求，生成並將其緩存到磁盤上。
它有效地產生了一個完美修剪的圖像，具有適當的尺寸，避免了不愉快的伸縮現象。
縮略圖不會修改您的博客或媒體庫。停用時，博客將恢復其舊有的行為。
第二個重要功能是對於缺少特色圖像的文章的自動選擇特色圖像。
您可以在不持久化選擇的情況下，即時選擇，或者為了更好的性能，在選擇一次后持久化選擇。
請閱讀 縮略圖 的官方頁面以獲得詳細信息。
主題開發人員可以找到使用說明（不需要撰寫與縮略圖相關的代碼！）。

原文外掛簡介
WordPress themes need thumbnails in different sizes and they even let the user to change those dimensions.
But WordPress has a problem: it does not regenerates the thumbnails when new sizes are registered.
Thumbnails intercepts the request by themes or plugins to WordPress to get a specific thumbnail, generates it and caches it on disk.
Efficiently, it produces a perfectly cropped image, with the right dimension avoiding unpleasant stretching.
Thumbnails does not modify your blog or your media library. When deactivated the blog returns to its old behavior.
The second important feature is the autoselection of featured image for post which are missing it.
You can choose between the on the fly selection without persist it or, for better performances, to persist it once selected.
Read the Thumbnails official page for detailed information.
Theme developers can find instructions to use it (no code tied to Thumbnails needs to be written!).
