Try something like this:

  # pipe list of jpg's to while loop
  find . -name \*.jpg -print | while read i
  do 
	# calculate filename w/out extension
    dir=`dirname $i` 
    base=`basename $i .jpg`
    file="$dir/$base"

	# update and rename file
    echo sips -s format bmp "$file.jpg"
    echo mv "$file.jpg" "$file.bmp"
  done

Remove the "echo " parts when you are satisfied the command will do what  you expect.

Actuall, I've not used it.  I rely on ImageMagick for such things.
