remove exif data on MacOS

I was look at how to remove exif data from photos I had copied to my Mac. I used AppleScript to achieve this:

To use this:

1. Open Script Editor on your Mac (found in Applications > Utilities).
2. Paste the script
3. Hit the run button

This script lets you select one or more images, uses the sips command with the -s formatOptions none option to remove the metadata. It makes a backup copy of the image with .backup extension.
