You don't mention what you're using, but if you're using perl to process the
files, you can do something like the following. . .

  $lc_tag = lc($tag); $file =~ s/$tag/$lc_tag/g;

Then, for moving the image files and rationalizing the filenames, you can do
something like the following:

  for i in `\ls images/*.gif`; do
    j=`echo $i | tr 'A-Z' 'a-z'`
    mv $i $j
  done
