In my opinion, there are some nice images on this site as well. I believe the low resolution version of the images belong to the paper copyright holders while the high resolution versions belong to some combination of the photographers, my co-authors and myself. I am looking into this issue and will post a statement as soon as I can get a clearer determination.
