I suggest walking into any Apple Store and asking one of their staff to show you how to store pictures you take with your iPhone. You can store your pictures on the iPhone itself - they'll show you where to find them on your iPhone - and you can also store your pictures in iCloud, which makes it easy to send your pictures to your family, even to members of your family that use Windows computers. They can explain that as well. They probably even offer a class on that, since so many people are asking about it.
Here in Microsoft Community, we try to help each other with questions about Microsoft products. The iPhone, as you know, is an Apple product.
I hope I'm still able to take pictures with my phone when I get to be 88! Bravo to you.
