        targetHeight: 500,

        vm.newPhoto = true;

    }, function (err) {
        console.log(err);
        vm.newPhoto = false;
        alert("Buddy Connector", "Error Getting Photo " + err);

}

What to do if I want to select multiple photos from photo library?? It allowes only 1 photo to be selected at a time.
