Thanks to both of you
@liftmeup78 Google Photos is very handy indeed, and easy to use with a great user interface. 15 GB is enough for photos, but not for videos. Maybe I'll consider multiple Google accounts.
@forevernow I need around 40 GB, mainly because of videos. So far, I found that degoo.com offers 100 GB for free. I'm just testing it out and will let you know my impressions.
