This is an interesting problem... my first reaction is that you'd want to use onComplete to update the div's instead of onSuccess.
Test this with a couple of alerts and see which one gets called first and which is last (just as onCreate is the first call, onComplete is the last). To my way if thinking, if you wait until onComplete gets triggered before you do any UI updates, all the images on the server should be properly in place.
