Everything else that loads it fine also seems to use libjpeg. It could be a bug in HOW emacs uses libjpeg. Firefox, gimp, gwenview, and even 'jpegtopnm | pnmtoxwd | xwud' all work. The one other tool I found which doesn't handle these images correctly is xli, which bails out without even trying: /home/epg/Downloads/adn.kingfeatures.jpg is a 2047x597 JPEG image, color space YCCK, 4 comps., Huffman coding jpegLoad: weird output color space zopen: warning: caching was disabled by previous caller /home/epg/Downloads/adn.kingfeatures.jpg: unknown or unsupported image type Light googling suggest YCCK may be an odd duck, and may be what throws emacs for a loop...

Looks like some problem with libjpeg: I can only see the problem if I disable the use of MS-Windows native image APIs (which forces Emacs to use libjpeg instead). With the default setting of w32-use-native-image-API on MS-Windows the saved image displays correctly.
