#tooltip{position:absolute;}
</style>
<script type="text/javascript" src="./script/jquery-1.4.2.min.js"></script>
<script>
$(function(){
var x = 10;
var y = 20;
$("a.tooltip").hover(function(){
var title = this.title;
$("a.tooltip").attr("newTitle",this.title);
this.title = '';
var $div = $("<div id='newTip'><img src='"+this.href+"'/><br/>"+this.newTitle+"</div>");
$("body").append($div);
$div.css({"position":"absolute","background":"silver"}).show("fast");
},function(){
this.title = this.newTitle;
$("#newTip").remove();
}).mousemove(function(e){
var $div = $("#newTip").css({"left":(e.pageX+x)+'px',"top":(e.pageY+y)+'px'}).show("fast");
});
})
</script>
