Hi, @jonsneyers
I tried looking for image/jxl in the IANA list, but it's not there. I see other JPEG formats like image/jxs and image/jxr are in the list.
Maybe image/jxl is registered under other name in the list? Let me know if you have any idea. I will use image/jxl if you don't. Thanks!
It's currently still on the 'provisional' list: https://www.iana.org/assignments/provisional-standard-media-types/provisional-standard-media-types.xhtml
Might take a while before it gets moved to the main list, I don't know at what pace IANA approves new media types...
1) Specify the MIME type and extension for which to add support image/jxl .jxl
2) Share an example file http://jpegxl.info/logo.jxl
3) Optionally, add a reference to the specification of the file format. ISO/IEC 18181 http://jpeg.org/jpegxl
