将远程服务器上的图片保存在本地空间

找到mysessiondata(37)=Content

改为

mysessiondata(37) = ReplaceRemoteUrl(Content)

如果希望是管理员才能有这权限，则修改为

if dvbbs.master then

mysessiondata(37) = ReplaceRemoteUrl(Content)

else

mysessiondata(37) = Content

end if

在文件的最后一行End Function后面增加

这一功能是参考动力文章系统修改而来，能将复制过来的网页上的图片，在发表的同时保存在自己的空间，在我自己论坛上测试成功。但是不敢确定这一修改方法是否会带来什么不良影响，请大家指正。

对于空间小的用户来讲，请不要使用或者只修改为管理员可以使用，否则，所有图片存入本地空间，空间容量将会承受不住。
