Alternative would be netpbm tools (script is called scalejpeg):

        #!/bin/sh

        TMPEXIF=$(mktemp /tmp/exifXXXXXX)
        TMPJPEG=$(mktemp /tmp/exifXXXXXX)

        jpegtopnm -exif=${TMPEXIF} $1 2>/dev/null | pnmscale 0.25 \
        | pnmtojpeg -exif=${TMPEXIF} > $TMPJPEG \
            && mv $TMPJPEG $1
        chmod a+r $1
        rm -f $TMPEXIF

Use it like

for img in *.jpg ; do scalejpeg $img; done

Best,
