[jQuery] How to determine number of elements after dom manipulation ?

[bakman]

I am generating elements (img's) based on data from an xml file.
Once that is done, I want to determine the number of icons that were
generated.

as naive as i am, i do a: alert($('img').size())
result: 0, which isn't the case

how can i determine them after they have generated ?

function dataloader(location,service,div){
        $.ajax({
                type: "GET",
                url: "includes/data.xml",
                dataType: "xml",
                success: function(xml) {

                        $(xml).find('group').each(function(){
                                if($(this).attr("name") == service){
                                $(this).find("Service").each(function(){
                                var type = $(this).find("Type").text()
                                var host = $(this).find("Host").text()
                                var name = $(this).find("Name").text()
                                var site = $(this).find("Site").text()

                                if(type == "Host" && site == location){
                                        $('<img src="images/server.jpg" 
title="'+ host +'" />').appendTo
('#'+div);
                                }
                        })
                        }
                        });
                }
