You can also automatically strip exif data from jpegs. Saves a bit of data, and can occasionally prevent an unintentional leak of embedded geo information.
# autorotate if desired
jhead -autorot name.jpg
# jhead can also strip exif data, but for some reason (can't even reall why)
# I have always just used jpegtran directly
jpegtran -copy none -optimize -perfect -outfile name.jpg name.jpg
