I think this is amazing, I wish more services would adopt this. I hate when I'm on Amazon or Newegg and I'm zoomed in just enough to where I can read things, but as I drag my way around an image it has to re-render it numerous times (even if I "go back" to a spot). I guess Amazon and Newegg are attributing for bandwidth wasted loading an entire image that may not be looked at? Not sure. Still love this.
