I have a MacBook with Mac OS X 10.5.6, Photoshop CS4, and a Canon Pixma all-in-one scanner/printer. I also have a pile of pictures to scan which I'd like to do automatically. I'm thinking of just putting that pile in the feeder and let it scan and save all the pictures automatically. However, pictures will usually get tilted when scanned via the feeder. Is there any method or software that will allow me to scan, crop, rotate, and save them all automatically at once?

If you have Windows-only solutions, let me know as well.
