Photoshop would be the best for the job, but there are other photo editing tools just as good. Check out this site: http://www.gimp.org/ . It has a free downloadable program. It not a good as photoshop but it comes close for what your trying to do.

use photoshop...you can download a free 30 day trial at adobe.com. And to get nice clear pictures you can either take them from google images, make sure you go to the scroll menu and click large. Or if you have a digital camera you can take pictures and upload them to your computer.
