I wonder, why nobody uses tiff2ps and gs for this task, as they are 
already installed with hylafax.

excerpt from my faxrcvd:

---- somewhere before mail-creation ------

PAGES="`$INFO -n $FILE | grep Pages | awk -F": " '{print $2}'`"
PREVIEWPAGES=1

if [ "$PAGES" -lt "$PREVIEWPAGES" ]; then PREVIEWPAGES=$PAGES; fi

#### create png-file from tiffg3 for preview
$TIFF2PS -a -O $FILE.ps $FILE > /dev/null 2>&1
$GSRIP -q -dBATCH -dNOPAUSE -dSAFER -r98 -sDEVICE=pngmono 
-sOutputFile=$COMMID%d.png $FILE.ps > /dev/null 2>&1

--- during mail-creation

## attach preview in PNG-format
         for ((page=1;page<=$PREVIEWPAGES;page++)); do
         echo "--$MIMEBOUNDARY"
         echo "Content-Type: image/png"
         echo "Content-Description: FAX Preview"
         echo "Content-Transfer-Encoding: $ENCODING"
         echo "Content-Disposition: attachment; 
filename=\"preview$page.png\""
         echo ""
         $MIMENCODE $COMMID$page.png 2>/dev/null
         done
# set the final MIME-boundary
         echo "--$MIMEBOUNDARY--"
        ) | 2>&1 $SENDMAIL -ffax -oi "$SENDTO"
    fi
else
    #
    # Generate notification mail for a failed attempt.
    #

--- at the end cleanup

if [ -f $FILE.ps ]; then rm -f $FILE.ps; fi
rm -f $COMMID*.png
