How to save pictures when starting?

I would like to restart my phone so completely, but I have pictures on the phone that I would like to keep in the new system, my laptop is unfortunately broken.
Do you have ideas?

Install the Google Photos app, upload your pictures there. Then re-install the app after resetting your phone. Log in again, and all pictures are instantly accessible again.

And if you have a new laptop, and you then open your Google Photos account then you have your pictures there as well.

And if you then make new pictures with your phone, you have almost the same again on the new laptop.

* note, however, that the images are then stored on servers. Especially if you have no talent for secure passwords, you should therefore delete sensitive images beforehand.
