Watermark script

I was asked to create a script to scale down, correct the rotation and add a watermark to a bunch of photos, here's the result.

This script will shrink the images by 25%, then it will check the rotation based on the exif information and finally, it will apply a text watermark, a logo image can also be used, check the commented lines.

#!/bin/bash
if [ -z "$1" ]
then
    location=$(pwd)
else
    location=$1
fi
#Address of the watermark file\r\n
#WATERMARK="/home/ldavim/Desktop/watermark.svg"
# Check if the directory "watermarked" exists or create it.\r\n
if [ ! -e "${location}/watermarked" ]
then
    mkdir ${location}/watermarked
fi
echo "Applying watermark, resize by 25% and rotate by exif info..."
#loop inside all the images in folder\r\n
for image in $location/*.jpg $location/*.JPG $location/*.jpeg $location/*.JPEG $location/*.png $location/*.PNG
do
    if [ ! -e "$image" ] # Check if file exists.\r\n
    then
        continue
    fi
    newImage=${location}/watermarked/$(basename "$image")
    #Scale image by 25%
    convert "${image}" -resize 25% "${newImage}"
    #Retrieve size of the image and divide the lenght by 2\r\n
    size=`identify -format %[fx:w/76] $newImage`
    #Correcting image rotation
    exiftran -a -i "${newImage}"
    #Apply the watermark and create a new image in the "watermarked" subfolder\r\n
    ##Using an image overlay
    #composite -dissolve 20% -gravity southeast -background none \( $WATERMARK -geometry ${size} \) ${image} "${newImage}"
    ##Using Draw text
    #convert "${newImage}" -font Sketch-Block-Bold -pointsize ${size} -draw "gravity southeast fill white text 0,12 'www.STYLETRACES.com' fill black text 1,11 'www.STYLETRACES.com'" "${newImage}"
    ##Using annotations
    convert "${newImage}" -pointsize ${size} -font Sketch-Block-Bold -fill rgba\(255,255,255,0.3\) -gravity southeast -annotate 270x270+7+251 'www.STYLETRACES.com' "${newImage}"
    convert "${newImage}" -pointsize ${size} -font Sketch-Block-Bold -fill rgba\(1,1,1,0.3\) -gravity southeast -annotate 270x270+8+250 'www.STYLETRACES.com' "${newImage}"
done
echo "Done."
#If you have installed zenity, a message will popup when the process is complete\r\n
