The name of all buttons is empty.gif and the size is also the same, I had tried various methods to click but all were unsuccessful! The source code can be get from attachments.Some relevent codes are here:

<div class="dtdh_box" style="z-index:1001">

<a href="javascript:;" onclick="goToMaps(1);return false;" class="dtdh_btn_lt"><img src="http://s23.dg.mop.com/images/empty.gif" width="39" height="42" /></a>

<a href="javascript:;" onclick="goToMaps(2);return false;" class="dtdh_btn_rt"><img src="http://s23.dg.mop.com/images/empty.gif" width="39" height="42" /></a>

<a href="javascript:;" onclick="goToMaps(3);return false;" class="dtdh_btn_lb"><img src="http://s23.dg.mop.com/images/empty.gif" width="39" height="42" /></a>
