Moving thumbnails; photogallery tutorial

Anyone?

referring to this tutorial:
http://www.kirupa.com/developer/mx2004/thumbnails.htm

I took the photogallery and thumbnail tutorial and left everything the same only now i have a larger size document and i need to move the thumbnail area to the bottom right corner – But when I do that, the thumbnails dissappear. I tried looking through the code and am not sure if it has defined a specific area for the thumbnails to work, which seems like that may be the case. Any help is appreciated. Thanks!
