So you would (in the example above) be copying
b.jpeg => 0000000.jpg
e.jpeg => 0000001.jpg
g.jpeg => 0000002.jpg
i.jpeg => 0000003.jpg
...

This would ensure that the sort order was the same as the book order if you were to generate a slideshow of the directory.
I'll have to wait till later to test it. Another thing I thought about. The copy time for each jpeg, each jpeg is between 100KB to 250KB, so I would run into a copy time delay for each depending on the file size. However small. I don't expect it to copy the sequence of images in list.txt all at once, a delay for each copy might be needed? So as to not overload the computer with a sudden long list of copying to do

pfsinhdrgen(1)						      General Commands Manual						    pfsinhdrgen(1)

NAME

       pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.

SYNOPSIS

       pfsinhdrgen <sample.hdrgen>

DESCRIPTION

       This  program  reads  files  defined  in  given	hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
       brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.

       The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.

       HDRGEN script file is a plain text file in  which  each	line  contains:  <path_to_an_image>  <inverse_of_exposure_time_in_seconds>  <aper-
       ture_size> <iso_speed> 0

       In  most  cases	it  is	convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
       information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:

       <--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8  100  0  /var/tmp/images/img10.jpg
       76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen

EXAMPLES

       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in sample.hdrgen script.
