关于IdHttp的使用,该怎么处理

关于IdHttp的使用
现在需要写一个根据版本下载文件的程序，在网上看了一下就用IdHttp和NMHTTP的，现在想使用IdHttp去处理，小弟是第一次写这个，哪位大哥能给点提示什么的吗？有点源码的更好，谢谢

例如下载一张图片
TMemoryStream *MyStreamt = new TMemoryStream();
IdHTTP1-> Get( "路径 ",MyStreamt);
MyStreamt-> Seek(0, soFromBeginning);
TJPEGImage *jp = new TJPEGImage();
jp-> LoadFromStream(MyStreamt);
Image-> Picture-> Assign(jp);
jp-> Free();
MyStreamt-> Free();

TStringStream* ResponseStream = new TStringStream( " ") ;
TStringStream* sendStream = new TStringStream( " ") ;

//sendStream 赋值

IdHTTP1-> Host = "http://www.xxx.ccc "
IdHTTP1-> Port = 80;
IdHTTP1-> ProtocolVersion = pv1_0;
IdHTTP1-> Request-> Accept = "*/* ";
IdHTTP1-> Request-> ContentLength = sendStream-> Size;

IdHTTP1-> Post(url ,sendStream, ResponseStream );
IdHTTP1-> Disconnect() ;
