alright check it out guys. here's the script:
Code:
#!/bin/bash

ls -a1 *.$1 | sort -n | while IFS= read fname ; do
    #echo "mv $fname ${i}.${1}"
    mv -f "$fname" "${i}.${1}"
    ((i++))
done

and here's the outcome:
Code:
kumi@throne:atlas/images/photos % ls
gallery*           Luis Work 009.jpg  Luis Work 017.jpg  Luis Work 029.jpg  Luis Work 043.jpg  Luis Work 046.jpg  Luis Work 069.jpg
Luis Work 001.jpg  Luis Work 010.jpg  Luis Work 018.jpg  Luis Work 030.jpg  Luis Work 044.jpg  Luis Work 055.jpg  Luis Work 070.jpg
Luis Work 008.jpg  Luis Work 016.jpg  Luis Work 028.jpg  Luis Work 042.jpg  Luis Work 045.jpg  Luis Work 068.jpg  untitled folder/
kumi@throne:atlas/images/photos % ./gallery 
ls: *.: No such file or directory
kumi@throne:atlas/images/photos % ./gallery jpg
kumi@throne:atlas/images/photos % ls
10.jpg  12.jpg  14.jpg  16.jpg  18.jpg  2.jpg  4.jpg  6.jpg  8.jpg  gallery*
11.jpg  13.jpg  15.jpg  17.jpg  1.jpg   3.jpg  5.jpg  7.jpg  9.jpg  untitled folder/
kumi@throne:atlas/images/photos % ./gallery jpg
kumi@throne:atlas/images/photos % ls
10.jpg  11.jpg  12.jpg  13.jpg  14.jpg  15.jpg  16.jpg  17.jpg  1.jpg  2.jpg  3.jpg  4.jpg  5.jpg  6.jpg  7.jpg  8.jpg  9.jpg  gallery*  untitled folder/

i think we're close! i lost one image and it was on the first run. i didn't lose anything the second time, but the files were listed in a different fashion, which i thought was weird. anyway what do you guys see?

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
