GPStoPic apply to multiple files

Chulber_XL, thx for thi sversion. I tried it but all the information is not printed on the pictures. the black frame is too shorl also.

New Script - 2n version
Image

Old Script - 1st version
Image

If fixing is too complicated, I am satisfied with thee first versions, it works fine. How can you modify it in order to execute it on many jpg at the same time.
using this form
Code:
 ./GPStagtoPic.sh *.jpg

Old version of the script (OK)
Code:
source=$1
target=${1%.jpg}GPS.jpg

# get the image's size, width=$1, length=$2, you need adjust for your image,
# depand the output format of command identify


set -- $(identify $source |awk 'NR==1{split($3,a,"x"); print a[1],a[2]}')  

I_WIDTH=$1
I_LENGTH=$2
 
function maxwidth()
{
        MAX_WIDTH=0
        while read line
        do
                INFO=$(convert -size 1025x768 xc:lightblue -font times.ttf -pointsize 18 -fill none -undercolor white -annotate +20+100 "$line" -trim info:)
                WIDTH=${INFO##*XC }
                WIDTH=${WIDTH%%x*}
        [ $WIDTH -gt $MAX_WIDTH ] && MAX_WIDTH=$WIDTH
        done
        echo $MAX_WIDTH
}
 
 
MW=$(jhead $source| grep "GPS " | maxwidth)

let WIDTH=MW+10
HEIGHT=60
 
convert -size ${WIDTH}x${HEIGHT} xc:black plaque.jpg
composite plaque.jpg -geometry +5+$(( $I_LENGTH - $HEIGHT - 5 )) -dissolve 60 $source $target
 
CMD=$(jhead $source |grep "GPS " |awk -v width=$1 -v lngth=$2 -v tfile=$target '
NR==1{Latitude=$0}NR==2{Longitude=$0} NR==3{Altitude=$0}
END{
    printf "convert -pointsize 18 -font times.ttf -fill white "
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-46, 39, Latitude, 39
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-28, 39, Longitude, 39
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-10, 39, Altitude, 39
    printf "%s %s\n", tfile, tfile }')
eval $CMD

Newversion of the script (NOK)

Code:
#!/bin/bash
FONT=times.ttf
FONT_SIZE=18
 
# Get width or length from image info string
function getwl
{
  read WnL
  # Get 3rd word
  WnL=${WnL#* * }
  WnL=${WnL%% *}
  # Remove from + to end
  WnL=${WnL%%+*}
  # Width before 'x' Length after
  [ $1 = 'L' ] && echo ${WnL#*x}
  [ $1 = 'W' ] && echo ${WnL%x*}
}
 
function process_image
{
    source=$1
    target=${1%.jpg}GPS.jpg
 
    I_HEIGHT=$(identify $source | getwl L)
 
    # Fetch GPS info into array
    IFS="
    " GPS=( $(jhead $source | grep "GPS ") )
 
    MW=0
    for line in "${GPS[0]}" "${GPS[1]}" "${GPS[2]}"
    do
        WIDTH=$(convert -size 1025x768 xc:lightblue -font $FONT \
            -pointsize $FONT_SIZE -fill none -undercolor white \
            -annotate +20+100 "$line" -trim info: | getwl W)
        [ $WIDTH -gt $MW ] && MW=$WIDTH
    done
 
    let WIDTH=MW+10
    let P_HEIGHT=FONT_HEIGHT*3+6
 
    convert -size ${WIDTH}x${P_HEIGHT} xc:black plaque.jpg
    composite plaque.jpg -geometry +5+$(( $I_HEIGHT - $P_HEIGHT - 5 )) \
         -dissolve 60 $source $target
 
    convert -pointsize $FONT_SIZE -font $FONT -fill white \
        -draw "text 10,$((I_HEIGHT - FONT_HEIGHT*7/3 - 8)) \"${GPS[0]}\"" \
        -draw "text 10,$((I_HEIGHT - FONT_HEIGHT*4/3 - 8)) \"${GPS[1]}\"" \
        -draw "text 10,$((I_HEIGHT - FONT_HEIGHT*1/3 - 8)) \"${GPS[2]}\"" \
        $target $target
}
 
FONT_HEIGHT=$(convert -size 1025x768 xc:lightblue -font $FONT \
            -pointsize $FONT_SIZE -fill none -undercolor white \
            -annotate +20+100 "Testing" -trim info: | getwl L)
 
for file in $@
do
   process_image $file
done

Thx,
