下载后获取另一张图片

Question

我想在这里下载一些产品图片： “http://www.kelkoo.no/c-100334923-babyutstyr/merke/brio”
我用：

 WebClient webClient = new WebClient(); 
 string photourl = "http://r.kelkoo.com/r/no/12085413/100334923/162/162/http%3A%2F%2Fwww.jollyroom.no%2Fmedia%2Fcatalog%2Fproduct%2Fcache%2F5%2Fimage%2F200x200%2F9df78eab33525d08d6e5fb8d27136e95%2F1%2F3%2F138489_1.jpg/R8i4cK4LKSF.G4h1Vyz5UptpU1E3B6l5vcwIb_iyNHQ-";
 webClient.DownloadFile(photourl, Application.StartupPath + @"\image\" +i.ToString()   +".jpeg");

我得到另一个，一张空白图片！
希望得到你的帮助。

            string photourl = "http://r.kelkoo.com/r/no/12085413/100334923/162/162/http%3A%2F%2Fwww.jollyroom.no%2Fmedia%2Fcatalog%2Fproduct%2Fcache%2F5%2Fimage%2F200x200%2F9df78eab33525d08d6e5fb8d27136e95%2F1%2F3%2F138489_1.jpg/R8i4cK4LKSF.G4h1Vyz5UptpU1E3B6l5vcwIb_iyNHQ-";
            webClient.DownloadFile(photourl, Server.MapPath(@"\image\" +i.ToString()   +".jpeg"));
