Hello, open to ridicule here but hey OK. I'm a complete twat when it comes to anything techie but here goes. I have 643 photos in my Google account that will not back up because I have not enough storage. I have 2 phones and 2 email addresses. What / how / where do I delete photos, or emails from. Do the photos i delete get lost forever. Whats the difference between google photos and gallery. I do not want to add storage, I simply want to back up my photos and delete old photos I don't need. Thanks
