Diaporama problem

Hello, I tried several options to change the diaporama in my presentation page. When I follow the theme insructions, I have to go in the Diaporama options and click on image slider. Then I have put my 4 pictures (the ID number of the 4 pictures) that I want to display in my diaporama; but I only get points (as well as the < > to move the slider of the diaporama) on my homepage instead of my diaporama with the beautiful pictures. Can you please help me ?
