Topic: Cutting off the thumbnails

When I view my page on my computer (windows XP, using IE and Chrome) and my mothers computer (mac with safari)  the main picture and the thumbnails and titles show up fine, although there is a lot of extra space on the top and the bottom of the viewer before and after other html elements. But, when I look at it on my friends computer (windows vista using IE) the titles and captions don't show at all and the thumbnails on the top and bottom are cut off part way.

What my friend sees: http://www.crepemyrtlephotos.com/images/myrtle2.jpg

The actual site is http://www.crepemyrtlephotos.com

Any ideas how to fix this would be greatly appreciated.
