Welcome MzDiana! I use Microsoft Office Picture Manager to edit all of my photos. If you are using a recent version of Windows, this should be available to you. I scan as a jpg, and then right click on the file, select "Open with" and then pick Microsoft Office Picture Manager. When you use the Edit Picture options, you can easily crop, rotate, and resize photos really easily.
Hope you can get something to work for you! You found the right people to ask. I'm sure others have their own techniques, so if this doesn't work for you, there should be plenty of other options.

Could I have a receipt please?
