I see jpeg files listed after MakeMKV scans for title tracks.
Is there a way to get these jpegs? I select the box, but I don't see any jpegs in the resulting directory. They could be useful as cover art...

I've been wondering about this too

I used to always select them when ripping, and I thought Windows might show them as a preview image, but at the time it didn't, so I stopped selecting them.

Would be nice if MakeMKV dumped them as a separate .jpg file rather than / in addition to whatever the .mkf container allows.

I have also been wondering about this but assumed the file was used in some different way. Some clarification would be great.

If you browse the blu-ray disc itself, you'll probably find the jpeg is a background image for a menu or something. It's not a copy of the cover picture... that would make too much sense.
