Ideally, we would have something like "image/jp2" and/or "image/jpeg2000" in the accepts header, analogous to Google's Chrome which adds the "image/webp" entry in the accepts header. This would be extremely helpful so that server side image processing tools (like Thumbor) can "automagically" return images with the best possible encoding/compression. Please add this header. Thanks, Jason Ormand @ Vox Media 1102606 1 heynemann 2015-06-17 11:45:59 -0700 This would be really useful for us as well. Globo.com is a large portal in south america (+1B page views/mo). We have a big focus on speed. That's why we added Automatic WebP support for thumbor[1]. It would be awesome to have the same level of support for Safari (Mac OS, but even more pressing iOS). This would allow us to detect if a request can receive JPEG 2000 and if so vary our cache by the Accept header. Hope this gets implemented.
