These are "thumbnails" - the smaller versions of photographs which will load relatively quickly in your browser.  If you see one you like, click on it and it will open up the full size view.  You can then right click on the photo in order to save it, use it as wallpaper or print it.  When you are done with a particular photo, just hit the back arrow on your browser to return to this page.
