How can I reorganize the way the thumbnails display of this page?

Here is the link of the page: http://www.web-design-talk.co.uk/examples/5/
What I want is similar to the page from the link above. But instead of the
thumb nails display on the bottom of the bigger image, I want them to be
display on the right side (where the whole paragraph of
writing/description is located) and switch the whole paragraph of writing
to the bottom of the bigger image where the thumbnails are located.
Could someone show me how I can reorganize this page please. Thank you
very much!
