GoFuckYourself.com - Adult Webmaster Forum - Tech Batch watermark folder recursively with imagick composite?

I would like to watermark thousands of images. I am trying to do it with imagemagick.

Code:

composite -dissolve 40% -gravity SouthWest /path/to/watermark.png /path/to/input/file.jpg /path/to/output/file.jpg

This works well for individual files. I have also managed to write a sh script based on it to watermark images in a folder but I can't make it watermark images in the sub folders of that folder. Any ideas how to add recursion to this command? :Oh crap

The sh script is...

Code:

#!/bin/bash



WM=$HOME/path/to/watermark.png

STARTDIR="/dicecotry/of/pics" 



for imagedir in $( find $STARTDIR -type d )

do

  echo "Running in $imagedir ..."

  cd $imagedir

  file -i * | grep image | awk -F':' '{ print $1 }' | while read IMAGE

  do

    echo "Watermarking $IMAGE"

    composite -dissolve 40% -gravity SouthWest -quality 100 $WM "$IMAGE" "$IMAGE"

  done

done
