When I scroll down to File Sharing iPhoto is not in the list - why?

I am trying to share images from iPhoto iOS with iTunes. The process on the iPad seems to work fine. But when I sync the iPad to my MacBook Pro the images are not there.

In iTunes I click iPad - select the Apps tab - scroll down to File Sharing and iPhoto doesn't appear in the list of Apps sharing files. How do I get iPhoto to appear in that list?
