{..........................
,openpage:function(){$scope.go('images');}
...................
    }]);

and i have error says

$scope is not defined

Answer 1

It is undefined because you never defined it:

factory("$jrCrop",["$ionicModal","$rootScope","$q",function(t,i,e)

But you don't even want to use $scope inside a factory. You would access whatever is needed from the factory inside a controller which has access to $scope.

Look at this stack: Accessing $scope in AngularJS factory?

Also: You write $scope.go('images'); as if it should be $state.go('images'); unless you have a $scope function called go(). But, again you shouldn't be using either of those in the factory.
