Is modifying standard gallery access possible?

**Following Simon's tutorial:**
https://devdactic.com/how-to-capture-and-store-images-with-ionic/
$scope.images = [];
 
$scope.addImage = function() {
	// 2
	var options = {
		destinationType : Camera.DestinationType.FILE_URI,
		sourceType : Camera.PictureSourceType.PHOTOLIBRARY
		allowEdit : false,
		encodingType: Camera.EncodingType.JPEG,
		popoverOptions: CameraPopoverOptions,
	};
	
	// 3
	$cordovaCamera.getPicture(options).then(function(imageData) {
 
		// 4
		onImageSuccess(imageData);
 
		function onImageSuccess(fileURI) {
			createFileEntry(fileURI);
		}
 
		function createFileEntry(fileURI) {
			window.resolveLocalFileSystemURL(fileURI, copyFile, fail);
		}
 
		// 5
		function copyFile(fileEntry) {
			var name = fileEntry.fullPath.substr(fileEntry.fullPath.lastIndexOf('/') + 1);
			var newName = makeid() + name;
 
			window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(fileSystem2) {
				fileEntry.copyTo(
					fileSystem2,
					newName,
					onCopySuccess,
					fail
				);
			},
			fail);
		}
		
		// 6
		function onCopySuccess(entry) {
			$scope.$apply(function () {
				$scope.images.push(entry.nativeURL);
			});
		}
 
		function fail(error) {
			console.log("fail: " + error.code);
		}
 
		function makeid() {
			var text = "";
			var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
 
			for (var i=0; i < 5; i++) {
				text += possible.charAt(Math.floor(Math.random() * possible.length));
			}
			return text;
		}
 
	}, function(err) {
		console.log(err);
	});
}
**and display all the local pictures and videos:**

**Instead of accessing the standard gallery:**
sourceType : Camera.PictureSourceType.PHOTOLIBRARY

THANK ANY IDEAS !!!
