Force Regenerate Thumbnails


Force Regenerate Thumbnails 能讓網站管理員刪除現有全部圖片縮圖,並為網站上的圖片強制重新產生新的縮圖。

從 [工具] 管理選單重新產生全部縮圖。進入 [媒體庫] 的清單檢視模式可進行批次重新產生縮圖,在清單檢視中選取要重新產生縮圖的圖片,然後在 [批次操作] 下拉式選單中點擊 [強制重新產生縮圖]。如需為個別圖片重新產生縮圖,請點擊圖片清單縮圖下方的 [強制重新產生縮圖]。

This plugin is amazing and helped me delete thousands of images but I have too many (100k+, Yes I’m very productive) and it always end u failing after processing 80k-90k images. Is there a way for the plugin to start with the very first images uploaded and finish with the most recent ones ? That would be amazing ! Thank you for the plugin and looking forward to your answer, Best

It is MUCH more aggressive than the other thumbnails’ regeneration plugins. I can see a great use case if you want to free up hosting storage, that’s why I give 5 stars. Anyway, be careful because there are chance to have missing images on frontend depending on several factors. As dev says in the dashboard, take a backup before proceeding.
