Media Carousel is not working - and at you?

[JBorschti87]

Hi Guys,
Media Carousel doesn't work for me. When I add pictures they just don't show up. The same problems with a friend. All other functions work. How are you all doing? Can you currently create a media carousel and easily add pictures?
Or do I have to pay attention to something important?
Carousel, Slide Show and Coverflow doesn't work.
