 To use this script, you will have to install the package on your operating system that
-includes \textit{jpegtopnm} which is ususally \textit{netpbm}.
+includes \textit{anytopnm} which is ususally \textit{netpbm}.
 Example usage of this script follows:
 
-\qquad \texttt{jpeglist.sh outfile infiles*.jpg}
+\qquad \texttt{./imagelist.sh outfile infiles*.jpg}
+
+where \textit{imagelist.sh} is just the name chosen for this script which could
+be anything but has to be executable, \textit{outfile} is the sequence list
+that is created, \textit{infiles*.jpg} are the 
+format\_type files such as \textit{jpg} in this example. The xxxtopnm
+messages that show up can just be ignored such as: \texttt{jpegtopnm: WRITING PPM FILE and jpegtopnm: Error writing row.}
+You may have to edit this script to suit your needs or to include specific directory locations. See also \nameref{ssub:filelist_format}.
