We have 7 users who have created a website and uploaded their images.
On the front page of openscholar I see two rows of images, 5 images in the first row and 1 image in the second row.

How can I control how many thumbnail images to display on the front page of openscholar?
Also on the Harvard website, there is a orange colored nice badge called "Featured" along the image thumbnails. How can I enable that?
