How can I get rid of this?

Hi again It seems like I can't find a way to get rid of the 3 photos and text which is in the theme from the beginning, I don't what you call them, but it is the 3 photos with the text underneath like "Nepal Prayer Wheels", "Mount Everest" and "Nepal Yak Tibetan" The photos are not even in the Media Library, so how can they show up on the frontpage???
