This is a quote from chapter 4 on page 74:
...significant net saving in bandwidth by step 7. Remember, at that point, the non-ajax application reloaded all the thumbnail images, whereas the Ajax apps simply re-used images already held in memory.

I do not think that the code actually does this, at least not in the version in the book. It would be easy to add though.

Re: saving bandwith (chapter 4)
You're right - thanks. I've reworded it!
