Images saved from camera or photogallery are not persisting after updating the app

The images persist when the app is open and closed, but when the app is updated from studio, the images are no longer available. I this normal? Do I need to save them somewhere else?

function insertdb(z_image, z_path, z_id) {
 
                    var commons = require("/ui/db/db");
                    var db2 = commons.getDb_DDX();
                    var tracer = require("/ui/common/tracer");
                    var dbLog2 = tracer.createTracer('db2');
                    dbLog2.info('opening database');
 
                    dbLog2.info('starting BEGIN');
                    db2.execute('BEGIN');
                    dbLog2.info('starting insert');
 
                    db2.execute('UPDATE notes SET  z_image=?,z_path=? WHERE z_id= ?', z_image, z_path, z_id);
 
                    alert('Saved');
                    Ti.App.fireEvent("notes", setArray);
 
                    dbLog2.info('finished inserts');
                    dbLog2.info('starting commit');
                    db2.execute('COMMIT');
                    dbLog2.info('finished commit');
                    dbLog2.info('closing database');
                    db2.close();
                    dbLog2.info('database save complete');
 
               }

//checking if it is photo
                                   if (event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO) {
                                        anImageView.image = image2;
 
                                        var time = new Date();
 
                                        var name = 'name' + time.getTime() + '.png';
                                        var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, name);
                                        f.write(event.media);
                                        Ti.API.info('f.nativePath' + f.nativePath);
                                        insertdb(name, f.nativePath, prodCat);
 
                                   }
