FckEditor,远程图片下载,插件
有时候我们从其他网页上拷贝来的内容中含有图片，当原始地址失效后就会影响读者阅读。
所以我制作了这样一个插件，可以将远程图片保存到本地服务器。

今天转载了xiaozhuang朋友的文章同时从博客园服务器上下载了图片
演示见：http://www.devedu.com/Doc/DotNet/AspNet/AspNet-AjaxWCF-ServiceADONET-Entity-FrameworkShiXianShuJuLieBiaoShuJuShaiXuanFenYePaiXuShanChu.aspx
原理如下：
1.实现ICallbackEventHandler接口以用启用客户端回调。
2.从当前FckEdiotr内容分析出所有<img标签，取得src的地址。
3.回调下载到服务器。
4.返回下载后位于本服务器上的路径。
5.替换当前FckEdiotr内容内对应的<img标签的src属性。
其他废话不多说了，代码中都有注释。
如果您熟悉Fckeditor的插件工作流程，请继续向下阅读，另请不要留言要我直接提供下载，下面的代码已经可以完整调试了。
E:\IISROOT\FckTest\FckTest\fckeditor\editor\plugins\remoteimagerubber\remoteimagerubber.aspx
E:\IISROOT\FckTest\FckTest\fckeditor\editor\plugins\remoteimagerubber\fckplugin.js
配置一下fckconfig.js

2 使用单页模型(非代码后置)，是为了便于此插件部署，
3 不需编译成dll，只需拷贝remoteimagerubber.aspx 和 fckplugin.js 到plugn目录，
4 并配置一下fckconfig.js及相应的语言包，就可以使用了。
