Hi superlala45,
Welcome to the Apple Support Communities. I see you have some questions about iCloud Storage and photos.
To get started, what's the exact message you're seeing, and what happens when you try to back up your photos? Are you receiving the iCloud Storage alert on your iPhone, or computer? It does sound like you may be in need of more iCloud Storage space if your photos haven't uploaded from your iPhone to iCloud, but knowing the answers to these questions will help make sure that's the right way to go.
Also, when you try updating your iOS software, what exactly happens?
To answer your questions about storage, you are correct that 50GB of iCloud Storage is $.99 per month, and tax may apply as well. It's a monthly fee, and you can learn more about how to

.
Choose from a total of 50GB, 200GB, or 2TB. You can even share the 200GB and 2TB plans with your family. Your storage is upgraded immediately, and your monthly payment date reflects the purchase date for your plan. If you upgrade from one paid plan to another, we’ll cancel your existing plan and charge you the prorated cost* of your new, larger plan.
You're billed every month for your storage plan unless you downgrade your plan. Each month you'll get an email to remind you of your upcoming payment.
Whether you’re on an iPhone, iPad, iPod touch, Mac, or PC, upgrading your iCloud storage is simple. Choose your device below and upgrade in just a few quick steps.
