<ahref="javascript:void(0);"><imgclass="button1"onClick="javascript:document.body.style.background='url(images/bg/1.jpg)'"></a>
<ahref="javascript:void(0);"><imgclass="button2"onClick="javascript:document.body.style.background='url(images/bg/2.jpg)'"></a>

<ahref="javascript:void(0);"><imgclass="button4"onClick="javascript:document.body.style.background='url(images/bg/4.jpg)'"></a>
<ahref="javascript:void(0);"><imgclass="button5"onClick="javascript:document.body.style.background='url(images/bg/5.jpg)'"></a>
<ahref="javascript:void(0);"><imgclass="button6"onClick="javascript:document.body.style.background='url(images/bg/6.jpg)'"></a>
</div>
