if anyone could help it would be great!

What version of IE? It looks exactly the same in Firefox 5 and IE 9 (IE 9 in IE 8 mode) for me.
Other then font-size or course. Maybe that is the issue?

You page appears to have problems however: http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fwww.dannylintonphotography.com%2Fphotos.html

The page looks almost the same in chrome, firefox, and IE9. The only exception is IE7 which has much larger font for the page numbers.
