Options for displaying images in Spotlight

There are many ways of displaying the images in the results of a Spotlight search. There are three buttons in the blue "Images" bar. The first one displays the pictures as a slideshow. The second one displays the image as a list like any regular search. The most interesting one is the third one which displays the image as thumbnails to quickly preview and browse through your images. The "list" and the "preview" options are also available for PDF. The following screenshots show the three different buttons and the different way of displaying the results:
