I've noticed that Exiftool doesn't notice a thumbnail for a JFIF segment if said thumbnail is present. I'm sure this is a rare occurrence as most are probably stored in JFXX, but I found an example in the LG_KM330 sample jpg file.
Haven't heard back on this one. No worries just hope It wasn't forgotten.
You'll probably have to wait for Phil to get back. He went on vacation (https://exiftool.org/forum/index.php/topic,8409.msg43213.html#msg43213) a few days before you posted.
ExifTool was only extracting self-contained embedded images (ie. JPEG format).
But I will add the ability to extract these raw-data thumbnails in TIFF format. This will appear in ExifTool 10.60.
Thanks for the suggestion.

Awesome thanks. There was only one sample that I noticed which did such a thing.
Hello Phil, hello neebah,
I hope it is ok that I join this thread.
I know a little bit about the embedded thumbs like ThumbnailImage, PreviewImage or JpgFrmRaw image, which are all JPG.
But I need some private lessions on this embedded Tiff image.
As far as I understood this discussion, with Exiftool 10.60 it is possible to extract it with:
exiftool.exe -b -ThumbnailTiff -W thumb.tiff <imagefile>
Is this correct? If not, what is the command to extract it?
Thanks in advance
Best regards
Herb
Hi Herb,
Yes, this is the command. However, thumbnails like this are rare, so you won't see many of them.
