这是采集一条新闻，并将新闻中的图片保存到本机中去，再将html代码中的图片路径换成本机图片路径的例子。这个可适用于把编辑器中外网图片保存到本服务器上来。

上面是一些常用的函数，不要修改它

下面是使用上面的函数，保存图片功能
<%
url="http://www.aspbc.com/tech/showtech.asp?id=1109"
str=getHTTPPage(url,"utf-8")
str=ReplaceRemoteUrl(str, "pic/", "") '这里的pic是图片在本机上的文件夹
response.write str
%>

以上是采集新闻，保存图片功能，如果你要保存编辑器中的图片，改一下这个地方
url="http://www.aspbc.com/tech/showtech.asp?id=1109"
str=getHTTPPage(url,"utf-8")
改成
str=request("content")
就可以了，其他的不变
