Display EXIF metadata for JXL in Windows Explorer

[VcSaJen]

Windows Explorer displays JPEG metadata using Details Pane in main window or Details tab in Properties window.
It seems possible to add it for custom format using Property Handlers: https://learn.microsoft.com/en-us/windows/win32/properties/building-property-handlers

(Property Handlers implementation is there in https://github.com/saschanaz/jxl-winthumb/blob/main/src/properties.rs, what's not there is reading EXIF there.)

I agree with this request, there is a real need to support IPTC and EXIF in JPEG XL support, I m ready to sponsor this $$

sorry @saschanaz you redirected me about the question about wic / iptc / exif in windows file explorer, the reply is still not very clear ( not a programmer sorry ) . from my test, the exif aren't displayed ( my test reference is Adobe Bridge or ExiftoolGui )

when you replied :
Property Handlers implementation is there in https://github.com/saschanaz/jxl-winthumb/blob/main/src/properties.rs, what's not there is reading EXIF there.

what ( as a end user ) supposed to do ?

I'm afraid that as a user there's not much to do. I'm not sure what to do with a dev either, I requested help: tirr-c/jxl-oxide#381
