Mogrify compresses jpeg's at 75 on a scale of 100. Gimp, by default, also
saves jpeg's at 75. So, I wonder if the size difference is a result of
undergoing a 25% compression two times? You might try mogrify and
specifying a quality of 50 and see if you get comparable results--and save
yourself a step. I'm going to try it now.
