You have to enable animation for every Content Manager element.
To do that, go to Content Manager, click on “Edit” icon on element which you want to animate (e.g. Services – Carousel/List). Once a new modal dialog opens, you will see a link “Special options” at the bottom.
Click on it and you will see an “Element animation:” dropdown list.
Which images are missing? If you think on Revolution Slider, those you have on your website are the ones you get in the theme package.
