How to save image from direct local URL to File

In my recent project its an requirement to save images from URL to hard disk or any media. After binged I have got several solutions. Now sharing you the right solution which is work for me.

Code(C#):

protected void Page_Load(object sender, EventArgs e)
{
string url = "http://img510.imageshack.us/img510/5523/aspnet4jh.jpg";
string DestinationPath ="C:/temp";
string filename = url.Substring(url.LastIndexOf('/')+1);
byte[] bytes=GetBytesFromUrl(url);
WriteBytesToFile(DestinationPath +"/"+filename, bytes);
}

static public byte[] GetBytesFromUrl(string url)
{
byte[] b;
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(url);
WebResponse myResp = myReq.GetResponse();

Stream stream = myResp.GetResponseStream();
//int i;
using (BinaryReader br = new BinaryReader(stream))
{
//i = (int)(stream.Length);
b = br.ReadBytes(500000);
br.Close();
}
myResp.Close();
return b;
}

static public void WriteBytesToFile(string fileName, byte[] content)
{
FileStream fs = new FileStream(fileName, FileMode.Create);
BinaryWriter w = new BinaryWriter(fs);
try
{
w.Write(content);
}
finally
{
fs.Close();
w.Close();
}
}
