Slide Show Problem

Could someone please take a look at the .fla i’ve attached of a seemingly simple slide show and tell me what I’ve done wrong. I followed the tut http://www.kirupa.com/developer/mx/photogallery.htm but Ive messed it up somewhere because only a part of my pictures are showing up and they are not even centered on the mc how that is even possible I dont know. Thanks for the help!
