It’s really smart to keep your files in the cloud.  Google offers 15 gb of free storage. If you have a gmail all you have to do is log into google photos and you already have an account. You can also sign up for google photos without switching over to gmaii.

If you log into https://photos.google.com you can find all the shared photos there.  From there you click on the save button on the top right (cloud with a down arrow).  That way when I remove them after a month they will still be in your account.  If you don’t want to use google photos just make sure you download the whole set before the month is up.  Feel free to share the link around and let your family download as well.
