How to rotate multiple photos in finder

I have a number of photos that are the wrong orientation. I wanted to rind a way to rotate are large number of photos all at once. Finder doesn't have a rotate button ( not that I could find anyway )

So I Google'd it and found this ..

1. Create a new folder on your Desktop.
2. Right click (Control click) to Attach Folder Action.
3. You'll get the Folder Actions Scripts.
4. Go down to the Image-Rotate (left or right) and attach
5. Then just drop the images in that folder.
