What photo editing do you use? [View all]

I'm thinking I have to get rid of some of my stuff on ebay, but it's been more than 20 years since I've sold on the Internet. I have a decent camera, but I still need to crop, lighten, darken, etc. to have good photos to post. I'm kind of a technophobe, so looking for something easy to use. It doesn't have to have a million options because I only use a few. Thanks for any help.
