Dynamic content gallery – not looping

The Dynamic Content Gallery on my blog http://nataliecollinson.com
does not loop? If loop is the right word to use?

I only have a couple of posts in there, but once it has shown them, it stays static on the last image.

Is there a way to have it running on a continuous cycle / loop?

I am soooo new to blogging – answers in the most simplistic form would be hugely appreciated. Thank you so much :o)
