2.1 – Load images from database

In project 1, we saw how the <img> tag works. You provide a **src**
(short for source) attribute and the image gets loaded in.

Here we iterate through the images in the database and for each one, we
create an <img> tag with the **src** set to that image's URL.

2.1 – Create a new image

First create a route. Go to /images/new. It tells us we need to add a
controller action. So do that. Then refresh. It tells us we need to
create a view.

Then we create a form, like in project 1, to point to "/images". We
submit the form and see that no route exists for POST "/images". Note
that POST and GET to the same URL are considered different routes.

We add a route. It tells us that there's no create method in the images
controller.
