ASP通過函數來實現替換、保存遠程圖片，完成自動采集圖片、提取圖片的功能，函數中自動判斷重復圖片，智能分析鏈接路徑，并轉成成相對的圖片地址保存在你指定的網站目錄中，我們可將此函數用在后臺的編輯器中，當你復制了含有圖片的內容后，本代碼會自動幫你上傳圖片。同時本代碼也是采集程序中的重要處理函數，函數代碼如下：

Function ReplaceSaveRemoteFile(ConStr,strInstallDir,strChannelDir,SaveTf,TistUrl)

函數參數說明：
ConStr：要替換的字符串
參 數：SaveTf：是否保存文件，False不保存，True保存
參 數: TistUrl：當前網頁地址
