From a CSS standpoint, you’re site is very slick. If you want to make it a tiny bit faster, make more use of CSS sprites if possible. For example, The following images served from jeansbox.nl should be combined into as few images as possible using CSS sprites.
* style.jeansbox.nl/images/bg_select_o.gif
* style.jeansbox.nl/images/bg_tit_o.gif
* jeansbox.nl/wp-content/plugins/wp-postratings/images/stars/rating_half.gif
* jeansbox.nl/wp-content/plugins/wp-postratings/images/stars/rating_off.gif
* jeansbox.nl/wp-content/plugins/wp-postratings/images/stars/rating_on.gif
* jeansbox.nl/wp-content/plugins/wp-postratings/images/stars/rating_over.gif
Hope that helps.
