ASP.NET download remote image from remote server via http

I'm trying to download an image from a remote website via http.  What I've got so far is

WebRequest wr = WebRequest.Create(src);
Image img = Image.FromStream(wr.GetResponse().GetResponseStream());
img.Save("mydownload.gif");

I got this code from an example I found on online.  But the Image class doesn't seem to have a From Stream method.

How do I convert the response stream into an image that I can save to my web server?

Thanks
