Looks to me like the downloadFileFromUrl function is returning a *promise*,
not the data that you're interested in (results.data). Remember, $http.get
kicks off an asynchronous action - so it will return a promise that it will
resolve to a value at some point in the future. You could do something
like this:
function downloadFileFromUrl(url) {
$http.get(url).then(function(result) {
$scope.img = 'data:image/jpg...';
});
}
