Iphone Pictures

Is there a good method of backing up iPhone pictures without having a PC or Mac? My mother has a chromebook, she had upped her iCloud storage but keeps hitting her phones memory maximum. I believe its not possible to delete pictures from the phone without also deleting from the cloud is there?

Ideally, there would be another cloud based app that she loads her pictures too that allows her to delete the without the risk of losing them, has the ability to download them again in the future if needed, and can also be accessed through a chromebook so she can manage them easily.

Is there a good solution? I would think there were be a large population of people with way too many pictures for their phones memory.
