Upload Image from URI to Azure BLOB - asp.net

Question

I'd like to upload images from an uri postet to an asp.net mvc5 controller to azure blob storage. I already got it working with HttpPostedFileBase, like this. Can I somehow get the memory stream from an image uri?
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
var imgFile = System.Drawing.Image.FromStream(hpf.InputStream, true, true);
CloudBlockBlob blob = coversContainer.GetBlockBlobReference("img.jpg");
MemoryStream stream = new MemoryStream();
imgFile.Save(stream, ImageFormat.Jpeg);
stream.Position = 0;
blob.UploadFromStream(stream);

So this is how I managed to get it done:
public static Image DownloadRemoteImage(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (Exception)
{
return null;
}
// Check that the remote file was found. The ContentType
// check is performed since a request for a non-existent
// image file might be redirected to a 404-page, which would
// yield the StatusCode "OK", even though the image was not
// found.
if ((response.StatusCode == HttpStatusCode.OK ||
response.StatusCode == HttpStatusCode.Moved ||
response.StatusCode == HttpStatusCode.Redirect) &&
response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase))
{
// if the remote file was found, download it
Stream inputStream = response.GetResponseStream();
Image img = Image.FromStream(inputStream);
return img;
}
else
{
return null;
}
}
