Creating Pages
To make a page: enter your proposed page title in the searchbar. If it doesn't exist, it will give you an option to create the page!
Adding Images
To add an image: create an account, and select "Upload file" in the Toolbox, under the navbar. You can add uploaded images to pages however you see fit.
The image to the right also has some great information.
Note: for external links, it is one square bracket, not two (the anon made a mistake on this)
