$scope.processFiles = function(files) {
    angular.forEach(files, function(flowFile, i) {
        var fileReader = new FileReader();
        fileReader.onload = function(event) {
            var uri = event.target.result;
            var image = uri;
            var r = Math.floor((Math.random() * 225) + 4000);
            reg_photo = site_url + 'assets/sources/uploads/' + oneSignalID + '.jpg';
            var div = angular.element(document.getElementById('photo-upload'));
            div.css('background-image', 'url(' + image + ')');
            $('#photo-upload i').hide();
            con = true;
            $.ajax({
                url: site_url + 'assets/sources/appupload.php',
                data: {
                    action: 'register',
                    base64: image,
                    uid: oneSignalID
                },
                cache: false,
