Get a Google account and use Drive. Create a new folder, click Share. You can allow anyone with a secret link to add/delete/modify/or just view. Or you can specify only share with certain people whether through email address or password. Create a new folder for another year if you want or organize it however you'd like. I think you should give it a shot first before springing for a paid service.
