jQuery .load() not firing on images (probably caching?)

I have some pretty basic jQuery code:

...
$(this).find('img').load(function(){
   loadedImages++;
   if(loadedImages == $this.find('img').length){
...

However, thats not firing consistently. It fires if i do a hard refresh or close my browser, but a normal refresh, or just hitting the same URL twice at any time without erasing the cache makes the .load() never fire.

Any ideas on how to fix this?
