Flash slideshow problem

I am trying to set up a slideshow with flash, which I did, but when it plays, it doesn’t play all of the way through. Sometimes it goes halfway, other times less. Seems to be random. I am using macromedia and am a newby with this sort of stuff. Here is the page I am working on. http://cascadecrusades.org/cascadecrusades/hiking/ptarmigantraverse/pt2006/photoonly.htm

Thanks for any help.
