You'll have to do it within the success callback:

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);

}
  });
}
  });
  alert($('#' + div).find('img').length); // -- should give you  
correct number here

}
  });
}

where did you exactly call 'alert($('img').size())'? inside the callback
function? remember ajax is asynchronous, if you're calling it after calling
dataloader() the ajax mat not return yet and your images aren't yet in the
DOM.

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 ?
