Removes meta data (smushes) from jpegs in a specified folder and it's subfolders. Will only attempt to smush graphics that have been modified recently and will not touch images that it already smushed. It does this by creating a temp file and comparing the two. If there was any space savings it will overwrite the original.
Just adjust the parameters inside the script and run it. You may want to adjust the -mtime param in the find command.
