Perl comes with a rename command that handles this fairly well. Here are 
some ways of solving your problem both with and without rename (watch 
out for line-wrapping):

find E.DIR/ -name "*.[Jj][Pp][Gg]" -exec rename 's/ *\((\d+)\) */$1/g' 
"{}" \;


find E.DIR/ -name "*.[Jj][Pp][Gg]" -print0 | xargs -n3 -0 rename 's/ 
*\((\d+)\) */$1/g'


find E.DIR/ -name "*.[Jj][Pp][Gg]" -print | \
while read fn
do
    nn2=`echo "$fn" | sed -e 's/ *(\([0-9]\+\))/\1/'`
    mv "$fn" "$nn2"
done

For the solution that uses xargs, it's probably okay to remove the -n3.
