unfortunately you'll need download image , save locally. can refer image isolated storage

string filename = @"shared\shellcontent\backgroundtileimage.jpg"; if(trysaveimage(filename, "http://foo.com/bar.png")) {     uri uri = new uri("isostore:/" + filename, urikind.absolute);     // create tile if didn't find exists.     var tiledata = new standardtiledata     {         title = "my tile",         backgroundimage = uri,     }; }  ... private bool trysaveimage(string filename, string url) {     using (var store = system.io.isolatedstorage.isolatedstoragefile.getuserstoreforapplication())     {         try         {             var backimage = new image();             backimage.height = backimage.width = 173;             backimage.stretch = stretch.none;             backimage.source = new bitmapimage(new uri(url));             backimage.measure(new size(173, 173));             backimage.arrange(new rect(0, 0, 173, 173));             var image = new writeablebitmap(backimage, null);              string directory = path.getdirectoryname(filename);             if (!store.directoryexists(directory))             {                 store.createdirectory(directory);             }             using (var stream = store.openfile(filename, filemode.openorcreate))             {                 image.savejpeg(stream, 173, 173, 0, 100);             }         }         catch         {             return false;         }     }     return true; }
