Suprisingly it’s still not listed on Microsoft’s Open Specification Promise where Microsoft lists things it won’t sue over. Hopefully they will update that soon. My understanding from what I’ve read is that’s the intent.
It’s a pretty interesting thing going on. Video on the web has improved by leaps and bounds over the years from a tiny grainy video object that took a decade to load, to instantly loading and still improving quality Flash / Windows Media / QuickTime. Photos on the other hand have been using JPEG for pretty much a decade. Most photography buffs don’t seem to fond of JPEG because it can degrade picture quality, but still love services like Flickr.
Will JPEG XR spark a photo revolution by allowing better quality?
