內容簡介
如果你曾經對 WordPress 處理圖片大小調整感到煩惱，這個外掛就是為你而設的。
這個外掛的作用是優化圖片處理方式，只有在必要時才會調整圖片大小。也就是說，如果你的外掛或主題定義了很多圖片大小，它們不會在上傳圖片時（通常會進行調整大小），而只有當需要某個特定大小時才進行生成。
大小調整只進行一次，之後 WordPress 會正常提供圖片，因此不會影響性能。
此外，此外掛還包括一種方法來刪除先前生成的所有圖片大小（在安裝此外掛時對於具有許多現有媒體的網站很有用）。
要刪除在啟用本外掛之前生成的圖片大小，請前往＂工具 -> 刪除圖片大小＂，然後使用按鈕進行清理。
除此以外，你不需要做任何事情，外掛在後台靜默運作。
總之：
僅在需要時調整圖片大小
清理現有圖片大小
不影響性能
釋放你的主機空間

原文外掛簡介
If you were ever annoyed about the way WordPress handles images resizing, this is a plugin for you.
What this plugin does is it optimizes the image handling in such a way that images are resized only when they are actually needed. What that means is that if your plugins/theme define a lot of image sizes, none of them will be generated on the image upload (like they would be usually), but only if they are actually requested in that size.
Resizing is done only once, images are later normally served by WordPress, so there is no performance hit.
Plugin also includes a method for removing all of the previously generated image sizes (useful when you install this plugin on a site with a lot of existing media).
TO REMOVE image sizes generated prior to activating the plugin, visit the ‘Tools -> Remove image sizes’ and use the button to perform the cleanup.
Other than that, you don’t need to do anything, plugin works silently in the background.
To sum up:
Resize images only when needed
Clean up existing images sizes
No performance hit
Free up your hosting space
