Feature request jpeg 2000 accepts header

In the latest versions of Safari desktop/iOS, there is no specificity in image request headers that indicates the browser supports jpeg 2000. 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,

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.

Would really be useful to optimize performance for Safari
