Class pictures

I'm on a new computer so I don't have my photoshop (which is super old) to fix up my photos so I'm figuring out how to do it. I tried paint at first (wish I could smudge and blur instead of paint over things I want to not show) so that's why all the markings. Then I tried to see if I could improve the brightness and stuff when I saw you can do it with the photo thing microsoft has. Next time I'm going to try and see if I can do it all with photo. I'm not even sure it automatically saved/replaced the other photo - they don't look much better.
