How do I make photos from Google Photos or Google Drive available offline in bulk?

[AC Question]

I have around 800 photographs on my Google Photos (and backed up on my Google Drive) that I would like to download and make available offline so I can show them to family members that do not have Internet access.

I've searched and the only solution I was able to find was to select them one-by-one (I have over 800) and share them via Google Keep. I could find no other method of saving them in bulk.

There has to be an easy way to do this simple task? How can I store my photographs on my tablet (Nexus 9) so I can show them to people while offline? Thanks!

If you have Google Photos on your tablet and have synced all your photos, you will still be able to look at them all offline
