Newbie looking for some Help. I have a jpg file that contains Composite and FotoStation thumbnails and preview images. (See attached screen capture). I have been able to extract the composite thumbnail and preview images, but do not know how to extract the FotoStation thumbnail and preview images. Is there a way/command (I was able to extract the Composite images with the -b option) to extract the FotoStation thumbnail and preview images? Thanks in advance.
Sure. This command extracts the first ThumbnailImage:
exiftool -thumbnailimage -b FILE > thumb1.jpg
and this command extracts the second:
exiftool -copy1:thumbnailimage -b FILE > thumb2.jpg
You can use any group name that is different between the two tags to extract a specific ThumbnailImage/PreviewImage. The copy number group (family 4) is always guaranteed to be different, but in this case the specific location group (family 1) may also be different. You can use a command like this to see the group names for all tags:
exiftool -a -s -G4 FILE
this shows the copy number group names for each tag. Tags which are not duplicated do not have a copy number.

Phil,
Thank you for your response. Those commands got me what I needed. Thank you for exiftool.
