My iTunes stopped syncing with iPhoto

My iTunes stopped syncing with iPhoto, but I get no warning message. Just no update of photos. I do not believe i updated anything at the time that iTunes stopped syncing with iPhoto, its possible this coincided with one of the iTunes updates and i did not notice. I cannot see any new photos or albums in iPhoto in iTunes. How do I fix this? I already tried deleting the iPod photo cache in my iPhoto library. No luck. Any idea how to solve this?
