內容簡介
這個外掛會在上傳下載文件附件時，保護（壓縮）圖像文件。
當您透過下載檔案中的下載檔案區域，上傳圖像檔案時，它會以原檔案的形式進行上傳，並將其存檔為 .ZIP 格式。
然後，.ZIP 檔案格式會返回媒體資料庫，使用者選擇它，並插入到附件欄位中。
上傳時產生的原始圖像檔案在存檔為 .ZIP 格式後會被從檔案系統中刪除，這是預設行為。
選項
您可以使用幾個選項來更改它的行為。轉到下載 - 設置 - 擴充功能 - 保護圖像
覆寫 ZIP 檔案
強制覆寫已經存在相同名稱的 ZIP 檔案。如果取消勾選此選項且 ZIP 檔案已經存在（相同名稱），則不會進行存檔，會返回錯誤。預設值：未勾選
防止檔案刪除
在將圖像檔案存檔為 ZIP 格式後，避免刪除圖像檔案。如果圖像檔案需要用於其他用途，則在下一次刷新媒體資料庫時會列出圖像檔案。注意：這會建立兩個附件文章，一個是存檔為 ZIP 的，另一個是原始圖像檔案。預設值：未勾選
