I am able to upload images to a database using a form, however, I need to upload images via a direct url such as http://www.domainname.com/image1.gif

I understand that I may have to use WebClient  and Stream, however, I am not able to make it work.  I am using C#, ASP.NET 3.5.

Thank you for any feedback or advice.

Hello,
Use this code to get the array of bytes of the image.

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;
}

And use the following code to save it to disk.

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();
}

}

Also, forgot to mention about the sql part:

It is in C# too and you won't have problem integrating them.
TO put the image in sql database, just add one more function to what I already have mentioned to you.

Once you have the bytes array of the image, just use it as shown in this tutorial in the 'OnUpload' function.

I'm not re-writing it here as it is explained very well there. Just go thru once.

Hope it helped!
