Attached is an MPO sample from a developer posted from a Fuji 3D camera, where there should be two full images of the cat, one from the left lens, another from the right lens.  Even using -a -U -b -preview:all I just am not seeing a second image.  And... This is true for every MPO I have tested (about a dozen).

Does anyone know what might be going on?  I've read the spec and the ExifTool documentation without joy.

Actually, it looks like the first image isn't shown.  There's data for MPImage1 and MPImage2, but the only binary is MPImage2

* Did you read FAQ #3 and use the command listed there?
* Please use the Code button for exiftool code/output.
 
* Please include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).

MPImage1 is the primary JPEG image (starting at offset 0 -- the start of the file).

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
