There are multiple ways to display the content of your web site. Folder display options include "summary view", "tabular view", "thumbnail view", "standard view", and "select a content item as default view" (set a home page for the folder). You will find the display options in the green menu bar when you are logged in and on a folder.
By default, a folder will show you a list of what it contains ("standard view"). You can change the "display" of the folder to "select a content item as default view..." to show in place of the default list view.
