| Thanks Anthony. This command gets the job done. identify still reports 8 bits
depth but the file is indeed about half that of one with 256 colors - even if I

You can simpliefy that with IM...
convert /var/www/html/photos/cyclamin.jpg -resize 209x109 -colors 16 ppm:- |
ppmtobmp -bpp=4 > /var/www/html/photos/background.bmp
that is let IM do the work, then use NetPBM to get you that 4bit BMP
