THE MODIFIED SCRIPT FILE MAY GIVE YOU SOME ERRORS. Just ignore them for now. Before you panic and say it does not work, look and see if you have pictures. If you do, write down the directory path names. Go back to your text editor and substitute them for dcim/100msdcf/*.jpg in the script file. You may want to make several script files to handle the each of the different picture formats.
At this point the directory on your hard drive should look something like Section A.2. Enter this command to confirm it does:
[bash]$ dir -R name-of-your-picture-directory
The information in this document and the manuals and HOWTOs should get you up and running.
