If you are getting large volumes of traffic, you could create a system
where photos to be resized are added to a queue, then only processed at
a rate that doesn't affect the rest of the website. If you have control
over the thread priority of the resizing task, set it to idle or below
normal, then it only runs when the server has nothing else to do.
