To make it even easier to find maps that you can utilize in the classroom, Gallery has provided you with two options for the page layout.
The tile view is meant to allow you a better view of each map from the main list. This way you can find a map based on the look and feel of the image.
The card view was created to allow users to see more details about each map before navigating on to the detail page for the map itself. This view acts as an index that will make each image smaller, but provide more information up front while scrolling through the list.
