Here's another acronym: CMS. A Content Management System allows any stakeholder of a website to add, edit and manage content - images and pictures - on the website (as long as they have login details).
Having a CMS on your website means loads of great benefits:
A Content Management System is fantastic because it gives you as much or as little control over your website as you need. You can also have other members of your team use the CMS, but you can control their access privileges. So if you want them to be able to add text but not delete anything, that's easy to set up.
You're in control, and you can make your website your own.
