Any Picassa users out there? Looking for an alternative for my girlfriend.

My girlfriends laptop has been out of comission for a while but it just needed a new charger so she is back in business.

I think its from 2014 and I want to put linux on there as she already mostly used open source programs that are available on linux.

Her 1 program that she used to use often is Picassa. I see that Google has shut that down and I was hoping someone could recommend a program that functions similarly to picassa.

I've never used it before so I am unsure what functionality it had.
