It's amazing.
Just as a warning to others, Chrome (on an i7 iMac w/ 24GB or RAM) isn't very happy looking at the full-sized image. After scrolling a bit, it takes about 2 seconds to recover to let me scroll more. This was on Flickr's 'original size' view, but still HTML, not just viewing the JPG. Not sure if it's Chrome having issues, or the Mac (Mac tends to force color profile use on developers, and it may be reprocessing the entire thing each time I scroll).
