Title: Why Can't MC Open/Display these JPG's ?
Post by: tzr916 on December 22, 2023, 03:11:48 pm

What's wrong with these JPG's?

These JPG's all open perfectly in Windows 10 photo viewer and all other programs I try such as ZoomPlayer, VideoLAN, Windows Media Player, MS Paint, MS Paint 3D, Firefox, Chrome, Edged, Gimp, IrfanView, XnView, Darktable, Fotosizer, etc.

So why can't MC open them?

Thanks. I'm not proficient in github, but it appears that this error was reported to libjpeg-turbo in Jan 2019 and seems to be marked as "fixed". I guess JRiver should update it's libjpeg-turbo version, or tweak whatever "jpg driver" they are using?

These images should work in MC32 when it is released in a few weeks.
