All image thumbnails not showing

I have 9 images three rows of three, but only eight show up. I thought perhaps it was a bad file name but I'e ruled that out.
URL jeribooth.com/special-trips/chile/futa-lodge
number of shown images is set to 12.
I must be missing something.
Thank you for any help in advance,

OK I refreshed my browser a bunch of times thinking it was that. I have noticed Joomla (i'm Guessing) extensions with commands sometimes have a delay in showing in the front end. 3-4 minutes Has anyone else had this issue.

It's working now so sorry about that.
Rick
