If you've changed format with Gimp you'll love this
Code:

convert is part of Imagemagick ........... which is what my bbips stuff uses Smile
convert can do waaaayyyyy more than just switch the formats Very Happy Very Happy

Take a look at the bbips stuff ....... http://crouse.us/scripts/bash/bbips/

For example....... here is the bbips script to add borders to all your images....
Code:

#!/bin/bash
# FILE : bbborder.sh
# Function: Puts a border on all images in the directory.
# Copyright (C) 2024 Dave Crouse <dave NOSPAMat usalug.org>
# ------------------------------------------------------------------------ #
if [[ -z $( type -p convert ) ]]; then echo -e "ImageMagick -- NOT INSTALLED !";exit ;fi

if [[ -z "$1" || -z "$2" ]]; then
   echo " ";
   echo "      ######### COMMAND FAILED ########## ";
   echo "      USAGE: $0 bordercolor bordersize";
   echo "      EXAMPLE: $0 black 6";
   echo "      ######### COMMAND FAILED ########## ";echo " ";
   exit
else

export IFS=$'\n';
for i in $(find . -maxdepth 1 -type f -iname "*.jpg");
do
convert -bordercolor $1 -border $2x$2 ${i:2} _${i:2}
mv _${i:2} ${i:2}
echo "Created border on ${i:2}" ;
done
fi
exit 0


The line that does the work........
convert -bordercolor $1 -border $2x$2 ${i:2} _${i:2}
or used on a single image could look like.......

convert -bordercolor red 5x5 myimage.jpg newimagewithborder.jpg

convert and imagemagick are pretty darn slick Wink

Wow! Thanks stonecarver! That could come in REALLY handy if it works on my Mac. I've had to convert with AppleWorks SOO many times....it's annoying.
