Modification To Responsive Template Needed

We have a template which we will be using for a project, however we need some minor modifications to it.

The frontpage is here - http://www.temptationsdirect.co.uk/z/polishop/header-footer-3.html

You will see that the three images below the main slider do not shrink in width as the browser shrinks. We need them to shrink at the proper rate and then become stacked.

Also at http://www.temptationsdirect.co.uk/z/polishop/category.html we need space below the breadcrumb for a graphic which will be the full width but again will shrink in relation to the browser.
