<a href="javascript:void(0)" class="gog" alt="http://www.nvidia.in/docs/CP/26740/thumbs_googleearth.jpg" >earth</a>

<a href="javascript:void(0)" class="gog" alt="http://www.techbusy.org/wp-content/uploads/2011/10/block-websites-google-search-100x100.jpg" >block</a>

JQUERY

$(document).ready(function(){ 
    $(".gog").click(function(){ 
     $("#change").attr("src",$(this).attr("alt")); 
    }) 
})
