Why won't this jQuery loop work?

Why won't this work? All I did was put it inside a "while" loop

$(document).ready(function(){
	var i = 1;
	while(i <= 9){
		$(".mp-men" + i).click(function(){
			$("#display").attr("src", "01-bigthumb-" + i ".jpg");
		});	
		++i;
	}
});

Code (markup):

 

at first glance it looks ok, are you getting any errors in firebug or the error console?
