Steve, I don't know if you have resolved your issue yet or not, but just in case you haven't - - I have been using a free software called Picasa 3 for many years now. It is free, easy to use and can rotate photo's, lighten or darken them, spruce them up - you name it.
Give it a try. I think you will like it. I know I love the price!
