Not exactly the answer I know, but consider variations on this:
find . -type f | while read f 
do nf=$(echo $f | tr '[A-Z]' '[a-z]')
  mv $f $nf
done

to muck around with the bit JPG only, a variation of the above usng sed
will do nicely. You could also make them all .jpeg.

To impress/confound folk at the local LUG you can mung names by ROT13-
encoding the names. Repeating the transformation undoes the "damage."
