The intro paragraph can be added by going to the Template Display Settings tab and then scrolling down to the List Items section and entering the paragraph under the entry for List Introduction.
You can add the image (on the example page, this is the open Bible next to the words Bible Studies) in the Template Display Settings tab again, and scroll down to Front Page Images and make sure it is set to SHOW not hide. The image itself can be selected by going to the Administration tab and scrolling down to the Default Study List Image.
