Large gap between product image and thumnail images

Hi there,

I have looked online for an answer to this so I apologise if I have missed it. There is a gap between my product image and the thumbnails below it – see webpage here:

http://tombuckleydogportraits.co.uk/product/bullseye-limited-edition-bull-terrier-print/

I managed to reduce this gap by reducing the width of the div.summary box on the right to 55% (it was a value of px before), but I can’t figure out how to make the thumbnails sit directly below the product image. I think it may be a margin/padding issue but I am not too sure so would appreciate any help.

Many thanks,

Tom
