WP8 C# // Save image from web, in isolate storage -

i know how save image in isolate storage using following :

 private void addbutton_click(object sender, routedeventargs e)         {             memorystream stream = new memorystream();             writeablebitmap wb = new writeablebitmap(myimage, null);             bitmapimage bi = new bitmapimage();              wb.savejpeg(stream, wb.pixelwidth, wb.pixelheight, 0, 100);             stream.seek(0, seekorigin.begin);             string data = convert.tobase64string(stream.getbuffer());              appsettings.add("image", data);         } 

i know how load using following :

private void loadimage_click(object sender, routedeventargs e)     {         byte[] imagebytes = convert.frombase64string(appsettings["image"].tostring());          memorystream ms = new memorystream(imagebytes);         bitmapimage bitmapimage = new bitmapimage();         bitmapimage.setsource(ms);         myimage.source = bitmapimage;     } 

but don't know how load , read url, how can accomplished?

thx help.

from image url stream:

webclient client = new webclient(); client.openreadcompleted += (s, e) =>      {          byte[] imagebytes = new byte[e.result.length];          e.result.read(imagebytes, 0, imagebytes.length);           // can use returned stream set image source          var image = new bitmapimage();          image.setsource(e.result);          nlbi.thumbnail.source = image;      }; client.openreadasync(new uri(article.imageurl));
