Hi LovinQuiltin,
It would help if we knew what software you were using to alter your photos with so we can give you a step by step process.
If you don't have any software other than MS Paint that comes with Windows, then open your picture in Paint, go to Image (across the top, File, Edit, View, Image....) Select Stretch/Skew, and change the percent you want to reduce your image. Don't forget to save it. I would use Save As, that way, you will keep your original photo in case you need to go back to it again for something.
