Who can download this image with c# webrequest? -

image link : http://media.isna.ir/content/1435516708689_mehdi+ghasemi+%2818+of+18%29.jpg

and code :

webrequest req = webrequest.create("http://media.isna.ir/content/1435516708689_mehdi+ghasemi+%2818+of+18%29.jpg");  webresponse response = req.getresponse();  stream stream = response.getresponsestream(); image img = image.fromstream(stream); stream.close(); 

error message :

the remote server returned error: (500) internal server error.

but can see image in google chrome , firefox.

of course can download image website. why behavior of web site goes wrong?

this happens because servers reject requests don't specify user agent. change method pass user agent , work.
